Question

If you are asked to find 834/80, how do you know the quotient is greater than 10 before you actually divide. Please show work!

Answer 1

Well first when you look at the number 834, I hope you know your multiples of 10.. Cause 80 x 10 = 800. If you break up the question..

you would see 834/80 = 800/80 + 34/80
= 10 + 34/80 <--- Simplify
= 10 + 17/40 <--- Which is more than 10

Answer 2

800/80=10
834>800 so 834/80>800/34
so 834/80>10
