Question

The approximate populations of Idaho and Delaware (as of 2019) are listed below:
Idaho: 1, point, 7, 9, times, 10, to the power 61.79×10
6

Delaware: 9, point, 7, 4, times, 10, to the power 59.74×10
5

How many times greater was the population of Idaho than the population of Delaware? Write your answer in standard notation, rounding to the nearest tenth.

Answer 1

Idaho ≈ 1.79×10^6, Delaware ≈ 9.74×10^5.

Ratio = (1.79×10^6) / (9.74×10^5) = (1.79/9.74) × 10 = 1.838... ≈ 1.8.

So Idaho's population was about 1.8 times greater.
