Question

Mya has a picture that measures 10 inches by 10 inches. She uses a photocopier to reduce the size of the picture to 75% its original size. What are the dimensions of the picture after five reductions (reducing to 75% each time)? Round any decimals to the nearest tenth.

Answer 1

The dimensions would be 2.4 inches by 2.4 inches.

Explanation:

Answer 2

The dimensions would be 2.4 inches by 2.4 inches.

The easiest way to do this is to raise the percentage to the power of the number of times you want to decrease.


`.75^(5)` = .237

Then multiply that by the original size.

10 * .237 = 2.37

Then round to the appropriate number of places.

2.4
