I have an assignment and it is Compare Estimated Quotients. Estimate each quotient. Then write < or > in the circle to compare each pair of estimates.

Question

Please let me know how I would begin estimating decimal division?
76.3 divded by 8 and 37.6 divided by 7

Answer 1

80/8 =
35/7 =

Answer 2

Let me ask you. I guess what I don't understand is how did you get 80 and then 35? What is confusing me is that the number is 76.3 so I would have assumed with the .3 80 but then there is 37.6 and I was thinking rounding that up to 40. What am I not understanding?

Answer 3

I took the closest multiples of the divisors to make estimating easy.

Answer 4

Also with what you showed
80/8=
35/7=

Do you need to actually do the division and then determine which number is bigger or smaller?

Answer 5

In order to compare the estimates, you'll need to also do the actual division.

Which estimate is closer to the real answer?

Answer 6

80/8=10
35/7=5

10 > 5 would be the answer.

I would like to try and send a few more problems to see if I am on the right track with this.
Do the number behind the decimal not really matter when estimating?

Answer 7

Usually no.

Answer 8

Thank you so usually no the numbers behind the decimals don't really matter. I will keep that in mind.

Answer 9

You're welcome.
