5%

Explanation:

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

Answer 2

Percentage of books she read = 5%

Explanation:

Number of books brought = 90

Number of books read = 4.5

Percentage of books she read

={( 4.5) ÷ 90 } × 100

=

= {
`(45)/(10) ÷`}
`(90)/(1)`} × 100

=
`(45)/(10)` ×
`(1)/(90)` × 100

=
`(45)/(900)` × 100

=
`(1)/(20)` × 100

= 5 %

Percentage of books she read is 5%
