## Answers ( )

Answer:139.4%

Step-by-step explanation:To calculate the increase, divide 3.89 by 2.79.

3.89 ÷ 2.79 = 1.3943 <=Increase in decimal form.

Change the decimal form to percent by multiplying by 100.

1.3943*100 = 139.43%

Then round the answer to the nearest tenth, which is the first decimal place.

Rounding the first decimal place depends on the second decimal place, called the hundredth. If the hundredth is 0-4, round down (don’t change the tenth). If the hundredth is 5-9, round up (increase the tenth).

Since the hundredth is 3, round down.

139.43% ≈ 139.4%

There was a 139.4% increase.
