Question 1

⁹⁄₁₈ is equivalent to which fraction?

Accepted Answer

Answer

To find an equivalent fraction, divide both the numerator (9) and the denominator (18) by their greatest common factor, which is 9. This simplifies the fraction to 9 ÷ 9 = 1 and 18 ÷ 9 = 2, resulting in 1/2. This means that 9 out of 18 parts represents the same proportion as 1 out of 2 parts.

Question 2

2 ³⁄₄ + 12 ⁶⁄₈ =

Accepted Answer

15 ¹⁄₂

Answer

First, add the whole numbers: 2 + 12 = 14. Next, add the fractions: 3/4 + 6/8. Since 6/8 simplifies to 3/4, the sum of the fractions is 3/4 + 3/4 = 6/4. Convert 6/4 to a mixed number (1 2/4 or 1 1/2) and add it to the whole number sum: 14 + 1 1/2 = 15 1/2.

Question 3

789 - 32 =

Accepted Answer

757

Answer

To subtract 32 from 789, align the numbers by place value. Subtract the ones digits (9 - 2 = 7), then subtract the tens digits (8 - 3 = 5), and finally bring down the hundreds digit (7). This results in a final answer of 757.

Question 4

56 × 96 is closest to which value?

Accepted Answer

5,400

Answer

To estimate the product, round 56 up to 60 and 96 up to 90 or 100. Multiplying 60 by 90 gives 5,400. The actual product of 56 × 96 is 5,376, making 5,400 the closest value among the options.

Question 5

456 / 23 =

Accepted Answer

19.83

Answer

To divide 456 by 23, perform long division. 23 goes into 45 once, leaving 22. Bring down the 6 to make 226. 23 goes into 226 approximately 9 times (9 × 23 = 207), leaving 19. Adding a decimal and continuing the division, 23 goes into 190 approximately 8 times, resulting in 19.83 when rounded to two decimal places.
