Question

Solve the percent change . state if increase or decrease.

Answer 1

Answer:

1.) 18 is decreasing by 83%

2.) 16 is decreasing by 12.5%

Step-by-step explanation:

Part ÷ Whole = Percent (decimal form)

1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being decreased by 83%.

2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being decreased by 2%.
