Easy
What is the result of 12 + 7?
19
18
20
17
Adding 12 and 7 yields 19 because the sum of these two numbers is 19. This problem reinforces basic addition skills.
Which fraction is equivalent to the decimal 0.5?
1/2
1/3
2/3
1/4
The decimal 0.5 is equivalent to the fraction 1/2. Recognizing equivalent forms is essential in understanding numbers.
In the equation x + 5 = 10, what is the value of x?
3
4
5
6
Subtracting 5 from both sides of the equation x + 5 = 10 leads to x = 5. This demonstrates a simple method for solving linear equations.
What is the perimeter of a square with a side length of 4 units?
8
12
16
20
A square has four equal sides, so its perimeter is 4 times the side length. Multiplying 4 by 4 gives 16 units.
What is the value of 9 - 3?
5
6
7
8
Subtracting 3 from 9 results in 6. This problem practices basic subtraction, a foundational arithmetic skill.
Medium
Solve for x: 3x = 15. What is the value of x?
3
4
5
6
Dividing both sides of the equation 3x = 15 by 3 results in x = 5. This demonstrates a basic technique for isolating a variable.
What is the simplified form of the expression 2(3 + x)?
6 + x
6 + 2x
5 + 2x
2 + 3x
Applying the distributive property to 2(3 + x) gives 2*3 + 2*x, which simplifies to 6 + 2x. This reinforces understanding how to expand expressions.
What is the area of a rectangle with a length of 7 units and a width of 3 units?
10
21
24
30
The area of a rectangle is calculated as length multiplied by width. Multiplying 7 by 3 gives an area of 21 square units.
Which of the following is the best estimation of the fraction 3/8 in decimal form?
0.375
0.25
0.5
0.625
Dividing 3 by 8 yields 0.375, which is the decimal equivalent of the fraction 3/8. This skill is helpful in comparing fractions and decimals.
Simplify the fraction 24/36 to its lowest terms.
2/3
3/4
4/6
6/8
Both the numerator and denominator of 24/36 can be divided by 12, reducing the fraction to 2/3. This demonstrates the process of simplifying fractions.
Which property is illustrated by the equation 5 + 3 = 3 + 5?
Commutative Property
Associative Property
Distributive Property
Identity Property
The equation 5 + 3 = 3 + 5 shows that the order of addition does not affect the result. This is a clear example of the commutative property in action.
Solve the equation 2x + 3 = 11 to find the value of x.
3
4
5
6
Subtracting 3 from both sides of the equation gives 2x = 8, and dividing by 2 yields x = 4. This process shows how to solve simple linear equations by isolating the variable.
A ratio of 2:3 is equivalent to which of the following fractions?
2/3
3/2
2/5
3/5
A ratio of 2:3 means that for every 2 parts of one quantity, there are 3 parts of another. This relationship is expressed as the fraction 2/3.
Which of the following statements correctly represents the distributive property?
a(b + c) = ab + ac
a + (b + c) = (a + b) + c
a(b + c) = (a + b)(a + c)
a(b + c) = ab - ac
The distributive property allows one to multiply a number by each term within a parenthesis, resulting in a(b + c) = ab + ac. This is a fundamental property in algebra used for simplifying expressions.
Find the next number in the sequence: 5, 8, 11, 14, ...
15
16
17
18
The sequence increases by 3 with each term. Adding 3 to the last term, 14, gives 17, making it the next number in the sequence.
Hard
Solve for x in the equation 4(x - 2) = 2x + 6.
4
7
8
6
First, apply the distributive property to expand 4(x - 2) into 4x - 8. Equating 4x - 8 to 2x + 6 and solving for x gives 2x = 14, so x = 7.
If 3/5 of a number is 18, what is the original number?
30
25
28
35
Let the unknown number be n. Setting up the equation (3/5)n = 18 and solving for n involves multiplying both sides by 5/3, which results in n = 30.
Which expression correctly represents the area of a triangle with base b and height h?
bh
1/2 * b * h
2bh
b + h
The formula for the area of a triangle is 1/2 multiplied by the base and the height. This formula is a fundamental part of geometry.
If the perimeter of a square is 36 units, what is its area?
81
72
64
36
A square's perimeter is four times the length of one side, so a perimeter of 36 units means each side is 9 units long. The area is then 9 squared, which equals 81.
A student randomly selects a letter from the word 'MATHEMATICS'. What is the probability of choosing a vowel?
4/11
3/11
4/10
1/2
The word 'MATHEMATICS' has 11 letters, and its vowels (A, E, A, I) appear 4 times. Thus, the probability of selecting a vowel is 4 out of 11, or 4/11.
