Question

Use compatible numbers to estimate the quotient of 3780 ÷ 90. What compatible numbers did you use? Will your estimate be an underestimate overestimate? Explain why.

Answer 1

3780/90

what number close to 37 is divisible by 9 ? 36 !!

3600/90=40 or 3690/90=41

3780/90=42

this an underestimate because the compatible numbers 3600 and 3690 are less than 3780
