Estimating Quotients Quiz

Why is it important to use compatible numbers when estimating quotients?

• To make the numbers look nicer

• To ensure the result is a whole number

• To make the calculation faster

• To avoid using a calculator

In the stamps example, why can't we round 134 to 130?

• Because 130 is not a round number

• Because 13 divided by 5 does not result in a whole number

• Because 130 is too far from 134

• Because 130 is not divisible by 5

What compatible number is used to estimate 134 divided by 5?

• 120

• 140

• 130

• 150

Why is 700 not directly compatible with 9 in the second example?

• Because 700 is not divisible by 9

• Because 700 is already a round number

• Because 700 is too large

• Because the first digit 7 is too small

What number is 700 adjusted to for compatibility with 9?

• 710

• 740

• 720

• 730
