A c ompany purchased 3,128 bottles of water.Each departments needs 55 bottles.Which compatible numbers provide a better estimate
charle [14.2K]

Answer:

3,000 divided 60 are the compatible numbers, and the estimate is 50.

Step-by-step explanation:

Compatible numbers can be described as numbers which are close in value to the actual numbers and can easily be added, subtracted, multiplied, or divided mentally.

From the question, 3,000 divided 60 are the compatible numbers that provide a better estimate for the number of departments that can get the bottles because 55 can be rounded up to 60.

The estimate will therefore be as follows:

Estimate = 3,000 / 60 = 50
