NM-MSSA Mathematics — Questions and Answers
Question 1: What is the value of 7×(3+2)?
- 17
- 35 (Correct answer)
- 24
- 49
Correct answer: 35
To solve 7 × (3 + 2), you must follow the order of operations (PEMDAS/BODMAS). First, perform the operation inside the parentheses: 3 + 2 = 5. Then, multiply the result by 7: 7 × 5 = 35. Therefore, the value of the expression is 35.
Question 2: Which of the following fractions is equivalent to 3/4 ?
- 6/8 (Correct answer)
- 2/3
- 9/12
- 4/5
Correct answer: 6/8
Equivalent fractions represent the same value, even though they have different numerators and denominators. To find an equivalent fraction, you can multiply or divide both the numerator and the denominator by the same non-zero number. If you multiply both the numerator (3) and the denominator (4) of 3/4 by 2, you get 6/8, which is equivalent.
Question 3: What is the area of a rectangle with a length of 8 cm and a width of 5 cm?
- 13 cm²
- 26 cm²
- 40 cm² (Correct answer)
- 80 cm²
Correct answer: 40 cm²
The area of a rectangle is calculated by multiplying its length by its width. In this case, the length is 8 cm and the width is 5 cm. Therefore, the area is 8 cm × 5 cm = 40 cm². The unit for area is always squared, so the answer is 40 cm².
