write the percent equation then solve
a. 0.65% of 900 is what number? _________________________________
b. What is 0.6% of 75? __________________________________________
c. 85% of what number is 102?
a. 0.65% of 900 is what number?
Percent equation: 0.65/100 = x/900
Cross multiply: 0.65*900 = 100x
Divide both sides by 100: x = (0.65*900)/100
Solve: x = 5.85
Therefore, 0.65% of 900 is 5.85.
b. What is 0.6% of 75?
Percent equation: 0.6/100 = x/75
Cross multiply: 0.6*75 = 100x
Divide both sides by 100: x = (0.6*75)/100
Solve: x = 0.45
Therefore, 0.6% of 75 is 0.45.
c. 85% of what number is 102?
Percent equation: 85/100 = 102/x
Cross multiply: 85x = 100*102
Divide both sides by 85: x = (100*102)/85
Solve: x = 120
Therefore, 85% of 120 is 102.
