WIAT Mathematical Problem Solving & Computation 3

Question 1

A rectangle has a length of 12 cm and a width of 8 cm. What is its area?

Accepted Answer

96 cm²

Answer

Area = length × width = 12 × 8 = 96 cm².

Question 2

Order these fractions from least to greatest: 3/4, 2/3, 5/6.

Accepted Answer

2/3, 3/4, 5/6

Answer

Converting to 12ths: 8/12, 9/12, 10/12 — so 2/3 < 3/4 < 5/6.

Question 3

A spinner has 8 equal sections numbered 1–8. What is the probability of spinning an even number?

Accepted Answer

1/2

Answer

There are 4 even numbers (2, 4, 6, 8) out of 8 sections, so probability = 4/8 = 1/2.

Question 4

What is the least common multiple (LCM) of 6 and 9?

Accepted Answer

18

Answer

Multiples of 6: 6, 12, 18; multiples of 9: 9, 18 — LCM = 18.

Question 5

A tank holds 120 gallons. It is currently 3/5 full. How many gallons are in the tank?

Accepted Answer
