Explain how u did it

Answer 1

a. 37.5

b. 75%

c. 64%

d. 43.75%

Explanation:

a.
`(3)/(8)` =
`(x)/(100)`

Cross multiply

8x = 3(100)

8x = 300

x = 37.5

37.5%

b.
`(9)/(12)` =
`(x)/(100)`

Cross multiply

12x = 9(100)

12x = 900

x = 75

75%

c.
`(16)/(25)` =
`(x)/(100)`

Cross multiply

25x = 16(100)

25x = 1600

x = 64

64%

d.
`(42)/(96)` =
`(x)/(100)`

Cross multiply

96x = 42(100)

96x = 4200

x = 43.75

43.75%
