Answer:

a. 37.5

b. 75%

c. 64%

d. 43.75%

Step-by-step explanation:

a. [tex]\frac{3}{8}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

8x = 3(100)

8x = 300

x = 37.5

37.5%

b. [tex]\frac{9}{12}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

12x = 9(100)

12x = 900

x = 75

75%

c. [tex]\frac{16}{25}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

25x = 16(100)

25x = 1600

x = 64

64%

d. [tex]\frac{42}{96}[/tex] = [tex]\frac{x}{100}[/tex]

Cross multiply

96x = 42(100)

96x = 4200

x = 43.75

43.75%
