Question

A land developer sold 4 1/2 acres of his 15 1/5 acres. How many acres does he have left?

Answer 1

He has 10 7/1o left because 15 1/5-4 1/2=10 7/10! Glad to help anytime!

Answer 2

10 7/10

Because when you subtract, the denominators have to be the same. So to get the same, the only way you can go is up because 5 can't be divided by anything to get a whole number.

So the denominators have to be 10.

***But what you do to the bottom, you must do to the top.***

so 15 1/5 = 15 2/10 and 4 1/2 = 4 5/10 then subtract.

15-4=11 BUT 2/10 is smaller than 5/10 so the 11 will become 10 and the fraction would be 7/10 so your final answer is 10 and 7/10.
