Doug's height was 5 feet. The next year Doug was 5 feet 4 inches tall. What is the percent increase?

Answer 1

First step is to convert both 5 feet and 5 feet 4 inches into inches, which is 60 inches and 64 inches respectively.

Second step is to subtract 64 from 60 which is 4

Third is divide 4 by 60

The answer is 6.67% increase

This is how the Math will look:

new height (in inches) - old height (in inches) = 64-60 = 0.0666 = 6.67%

old height (in inches) 60

Answer 2

1. Convert all measurements to the same unit using the conversion 12 in = 1 ft. Height initial: 5 ft = 60 in, height final: 5 ft 4 in = 64 in.
2. Use the formula: height final / height initial - 1 x 100. 64/60 - 1 x 100
3. Final answer: Doug's height increased by 6.67%.

Answer 3

In order to calculate percent of increase, we can use the following formula:

big - small * 100

original



For this particular problem, we would want to start by coverting the height into inches. 5x12 = 60 inches. 60+4 = 64 inches. Now we can plug those values into our formula.

64 - 60 * 100 = 4 * 100 = 0.0666667 * 100 = 6.67%

60 60

This tells us that Doug's height 6.67% over the course of a year.

Answer 4

We first express Doug's old height and Doug's new height in terms of inches so that both heights are expressed in the same units. Since there are 12 inches in a foot, we can deduce that 5 feet = 5*(12 inches) = 60 inches and 5 feet 4 inches = 5 feet + 4 inches = 60 inches + 4 inches = 64 inches. We can also deduce that the amount of change = 64 inches - 60 inches = 4. Since the percent of change = [(amount of change)/(original amount)]*100%, we can conclude that the percent of change = [(4 in)/(60 in)]*100% = [(400 in)/(60 in)]% = [20/3]% = [6 2/3]% = 6.67% Thus, Doug's height increased by [6 2/3]% = 6.67% in one year.
