1.

`(4)/(5) = (16)/(20)`

2.

`(3)/(7) = (15)/(35)`

3.

`(4)/(3) = (12)/(9)`

4.

`(13)/(15) = (52)/(60)`

5. the enlargement will be 9 inches

`(w)/(15) = (3)/(5)`

multiply both sides by 15

`(w)/(15) (15) = (3)/(5) (15) \\ w = 9`

6. 12 cm

7. 16

`(4)/(2) = (16)/(8)`

4×4=16

8. 3.08

five u.s postal stamps cost $2.20 so we divide that by 5 to get the price of one which is $0.44

so $0.44 × 7 = $3.08
