Question

in our solar system, 6 of the 8 planets have moons. What percentenge of the planets have moons

Answer 1

Use the information to form a ratio... 6:8 or 6/8. Now set it equal to a ratio per 100...

6/8 = x/100

Cross multiply

8x = 600
x = 600/8
x = 75

75% have moons

Answer 2

if you divide 6 by 8 you get 75 %
