Question

When 64 is increased in the ratio 9 : 8, it becomes?

Answer 1

72

Explanation:

Since X : 64 = 9 : 8

Then we know X/64 = 9/8

Multiplying both sides by 64 cancels on the left64 × (X/64) = (9/8) × 64

X = (9/8) × 64Then solving for X X = 64 × (9/8)X = 72

Therefore 72 : 64 = 9 : 8

Answer 2

Recall that the ratio 9:8 can be written as follows:

`(9)/(8),`

therefore, when 64 is increased in the ratio 9:8 we get:

`64*(9)/(8)=72.`

Answer: 72.
