Question

Which of the ratios below has a unit rate of 25? Select all that apply.

A) 150:6
B) 75:3
C) 50:25
D) 3:90
E) 300:12

Answer 1

The ratios A, B, and E have a unit rate of 25.

Step-by-step explanation:

To find the unit rate of a ratio, we need to determine the value of one quantity in relation to the other. We can do this by dividing one quantity by the other. Let's calculate the unit rates for each of the given ratios:

A) 150:6
Unit rate = 150 ÷ 6 = 25

B) 75:3
Unit rate = 75 ÷ 3 = 25

C) 50:25
Unit rate = 50 ÷ 25 = 2

D) 3:90
Unit rate = 3 ÷ 90 ≈ 0.0333

E) 300:12
Unit rate = 300 ÷ 12 = 25

The ratios A, B, and E have a unit rate of 25.
