Question

Write the ratio as a fraction in simplest form with whole numbers in the numerator and denominator

64 hr to 72 hr

Answer 1

8/9

Explanation:

Find the HCF of 64 , 72

64 = 2 * 2 * 2 * 2 * 2 *2 = 2^6

72 = 2 * 2 * 2 * 3 * 3

HCF = 2*2*2 = 8

64 : 72 =
`(64)/(72)`

= 64 ÷ 8

72 ÷ 8

`=(8)/(9)`
