Question

Answer 1

149 girls

Explanation:

Answer 2

149 girls

Explanation:

Rearrange the Percentage Equation:

`T*p=F`

`F/p=T`

Where
`T` is equal to the original amount,
`p` is the percentage as a decimal, and
`F` is the final amount.

Percent to Decimal:

`86*0.01=0.86`

Applied Equation:

`128/0.86=148.8`

Since there can't be a 0.8 of a girl, round up to get 149.
