Answer 2

Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.

Explanation:

Renaldo will write
`(3)/(20)` as a decimal.

We need to choose methods he should use.

To convert fraction into decimal we need to make denominator the multiple of 10

If we multiply 20 by 5 we get 100, so multiplying the given fraction
`(3)/(20)` by
`(5)/(5)` because we need to multiply both by numerator and denominator

So,
`(3)/(20)\\=(3)/(20)* (5)/(5)\\=(15)/(100)\\=0.15`

So, Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.
