Question

Joe uses 16 pounds of fertilizer in his three gardens. He uses 3/8 of the fertilizer in his first garden and 1/4 of the fertilizer in his second garden. What fraction of the fertilizer is left?

Answer 1

Answer: The fraction of the fertilizer is left =
`\frac38.`

Explanation:

Given: Fraction of fertilizer used in first garden =
`\frac38`

Fraction of fertilizer used in second garden =
`\frac14`

Fraction of fertilizer used in third garden = 1- (Fraction of fertilizer used in first garden)-(Fraction of fertilizer used in second garden)

=
`1-\frac38-\frac14`

`=(8-3-2)/(8)\\\\=(3)/(8)`

Hence, the fraction of the fertilizer is left =
`\frac38.`
