Question

Write the ratio as a ratio of whole numbers in lowest terms $0.20 to $0.30

Answer 1

First, write the ratio as a fraction:

`(0.2)/(0.3)`

Multiply both numerator and denominator by 10:

`(0.2)/(0.3)=(0.2\cdot10)/(0.3\cdot10)=(2)/(3)`

Since both 2 and 3 are whole numbers and they don't have common factors, that's the ratio in its lowest terms.

Therefore, the answer is:

`(2)/(3)`
