Question

A rancher uses a bucket that holds 15,000 milliliters of water to fill a water trough for her horse. The trough holds 2.7 x 10^5 milliliters of water. How many buckets of water will the rancher need to fill the trough?

Answer 1

Step-by-step explanation:

the volume of the bucket is

15,000 = 1.5 × 10⁴ ml

the trough holds

2.7 × 10⁵ ml

by calculating how often the volume of the bucket fits into the volume of the trough, we will know how many buckets of water are needed :

2.7 × 10⁵ / (1.5 × 10⁴) = 2.7/1.5 × 10⁵/10⁴ = 2.7/1.5 × 10¹ =

= 27/1.5 = 18

the rancher needs 18 buckets of water to fill the trough.
