7.7
8.2
When adding decimals, line up the decimal points and add each column. The sum of 3.5 and 4.2 is 7.7, which is the correct answer.
What is 1/2 of 8?
5
4
3
4.5
Multiplying 1/2 by 8 gives 4 because half of 8 is 4. This basic calculation reinforces understanding of fractions.
Convert the fraction 1/4 to a decimal.
0.2
0.75
0.4
0.25
Dividing 1 by 4 yields 0.25. This conversion from fraction to decimal is a foundational math skill.

16
15
8
18
The perimeter of a rectangle is calculated as 2 times the sum of its length and width. Substituting the given values, 2*(5+3) equals 16.
In a class, the ratio of boys to girls is 2:3. If there are 10 boys, how many girls are there?
20
12
18
15
The ratio 2:3 means that for every 2 boys there are 3 girls. Since 10 boys represent 5 groups of 2, multiplying 3 by 5 gives 15 girls.
Simplify the expression: 3/4 + 2/5.
23/20
1/2
25/20
17/20
To add fractions, convert them to a common denominator. Here, 3/4 becomes 15/20 and 2/5 becomes 8/20; their sum is 23/20.
Simplify the algebraic expression: 2(x + 3) - x.
x + 6
3x + 6
x + 3
2x + 3
Distribute the 2 to get 2x + 6, then subtract x to simplify the expression to x + 6. This is the simplest form.
Solve for x: 3x - 5 = 16.
5
8
11
7
Add 5 to both sides to obtain 3x = 21, and then divide by 3 to find x = 7. This is a straightforward linear equation.
If 4 notebooks cost $8, how much do 7 notebooks cost at the same rate?
$12
$16
$18
$14
Determine the cost of one notebook by dividing $8 by 4, which gives $2 per notebook. Multiplying $2 by 7 results in $14.
What is the product of 0.25 and 12?
3.5
4
3
2.5
Since 0.25 is equivalent to one quarter, multiplying it by 12 gives 3, as one quarter of 12 is 3. This is an essential multiplication with decimals.
What is the area of a triangle with a base of 10 units and a height of 5 units?
30
25
50
15
The area of a triangle is calculated using the formula ½ * base * height. Substituting the given values results in ½ * 10 * 5 = 25.
Calculate the result of -3 + 7.
-10
10
7
4
Adding 7 to -3 is the same as subtracting 3 from 7, which gives 4. This problem reinforces the concept of adding negative and positive integers.
Find the area of a parallelogram with a base of 6 units and a height of 4 units.
10
20
30
24
The area of a parallelogram is found by multiplying the base by the height. Here, 6 multiplied by 4 gives an area of 24 square units.
What is the median of the set of numbers: [3, 7, 5, 2, 9]?
3
5
9
7
After arranging the numbers in ascending order (2, 3, 5, 7, 9), the middle number is 5, which is the median. This highlights the method for determining the median of a set.
What is 20% of 50?
12
20
8
10
Convert 20% to its decimal form, 0.2, and multiply by 50 to find the answer. The calculation 0.2 * 50 results in 10.
Solve for x: 2(x - 3) = x + 4.
10
7
12
8
First, distribute 2 to get 2x - 6, then set up the equation 2x - 6 = x + 4. Subtracting x from both sides and adding 6 yields x = 10.
If the ratio of 3x to 4 is equal to 9 to 8, what is the value of x?
1
1.5
2.5
2
Set up the proportion 3x/4 = 9/8 and cross-multiply to get 24x = 36. Dividing both sides by 24 results in x = 1.5.
A rectangle's length increases by 20% and its width increases by 10%. What is the percent increase in its area?
30%
25%
35%
32%
An increase in length by 20% gives a multiplier of 1.20, and an increase in width by 10% gives 1.10. Multiplying these factors (1.20 * 1.10) results in 1.32, which means a 32% increase in area.
Simplify the expression: 3[2x - (4 - x)].
9x + 12
9x - 12
3x - 4
5x - 4
Begin by distributing the negative sign inside the parentheses to obtain 2x - 4 + x, which simplifies to 3x - 4. Multiplying this by 3 yields 9x - 12.
A car travels 3/4 of a total distance in 40 minutes and the remaining 1/4 in 20 minutes. What is the ratio of the car's speed during the first part to that during the second part?
1:1
4:1
2:3
3:2
Speed is calculated as distance divided by time. For the first part, the speed is (3/4 of the distance)/40 minutes, and for the second part, it is (1/4 of the distance)/20 minutes. Computing these and comparing the speeds yields a ratio of 3:2.

Math Quiz: Algebra, 7th Grade & More Cheat Sheet

  1. Master the order of operations with PEMDAS - Think of PEMDAS as your superhero guide through tricky calculations. Always tackle Parentheses first, then Exponents, followed by Multiplication and Division (left to right), and finish with Addition and Subtraction (left to right). Practice makes perfect to avoid any chaotic math mix‑ups! GreatMN Schools
  2. Understand and apply properties of angles - Become an angle detective by learning that complementary angles add up to 90°, supplementary angles total 180°, and vertically opposite angles are always equal. Knowing these relationships helps you crack geometry puzzles faster than ever. Sketch, measure, and have fun spotting these angle pairs in everyday shapes! Big Ideas Math Answer
  3. Calculate area and perimeter of shapes - From rectangles to triangles, mastering these formulas lets you measure floors, walls, and even pizza slices with confidence. Remember area is how much space is inside (like length × width for a rectangle) and perimeter is the total distance around. Grab a ruler and turn every shape into a math exercise! Big Ideas Math Answer
  4. Grasp ratios and proportions - Ratios compare two quantities (like 3 apples to 2 oranges) and proportions show that two ratios are equal. This concept is your secret weapon for tackling scale drawings, recipes, and real‑world mixtures. Solve ratio puzzles and see how everything from maps to models clicks into place! Math Chimp
  5. Solve linear equations and inequalities - Dive into one‑step and two‑step equations to find unknown values with balance and logic. Inequalities add a twist by showing ranges of solutions (think "less than" or "greater than"). Practice isolating variables and watch algebra become your new best friend! CliffsNotes
  6. Explore exponent properties - Exponents let you express repeated multiplication in a snap (like 2³ = 2×2×2). Learn the rules - product of powers, power of a power, zero exponent - and you'll simplify expressions like a pro. Tackle those giant numbers without breaking a sweat! StudyPug
  7. Navigate the coordinate plane - Plotting points (x, y) is like giving locations a precise home on a grid. Learn how to read and interpret line graphs, scatter plots, and more to reveal trends and patterns. Soon you'll be graphing like a data wizard! GreatMN Schools
  8. Calculate surface area and volume of 3D shapes - From prisms to cylinders, surface area finds the total wrap‑around space, and volume measures how much fits inside. Use formulas like 2lw + 2lh + 2wh for prisms or πr²h for cylinders to solve real‑life problems - think gift wrapping or filling a fish tank! Big Ideas Math Answer
  9. Study the basics of probability - Probability predicts how likely events are, from flipping coins to drawing cards. Compare experimental probability (based on trials) with theoretical probability (based on outcomes). Play games, run experiments, and watch chance unfold in surprising ways! Math Chimp
  10. Convert between fractions, decimals, and percentages - Switch up forms to simplify calculations and real‑world problems like discounts or test scores. Remember that ½ = 0.5 = 50%, and practice converting back and forth until it feels natural. Master these skills to handle any numeric challenge thrown your way! StudyPug
