7. Write the percent equation. Then Solve.
a. What percent of 60 is 3.3? __________________________________
b. 30 is what percent of 24? _____________________________________
a. 3.3 is (x) percent of 60
b. 30 is (x) percent of 24
To solve for x in both equations, divide the given number by the total and then multiply by 100.
For equation a:
3.3/60 = x/100
Cross multiply:
60x = 3.3 * 100
Divide both sides by 60:
x = 3.3 * 100 / 60
x ≈ 5.5%
For equation b:
30/24 = x/100
Cross multiply:
24x = 30 * 100
Divide both sides by 24:
x = 30 * 100 / 24
x ≈ 125%
