Ross and Lydia estimate the quotient for 387.5 divided by 73. Ross uses a whole number greater than the dividend. Which equation shows how Lydia uses compatible numbers to get a closer estimate?
A. 400 divided by 80=5
B. 450 divided by 75=6
C 360 divided by 60=6
D 375 divided by 75=5
Thank you for the opportunity to help you with your question!
So the the following equation shows compatible numbers
thank you for your reply...can you explain why the answer is b?
Because as the dividend being assumed is greater than 387.5 as he is assuming a integer value greater than this. So the quotient will also be greater than 5.3. So there is only possibility B) Where 450> 387.5 and 6> 5.3
