Ahorse had 4 1/5 scoops of oats in his bucket he ate 2 1/2 scoops of oats how much scoops of oats are left in his bucket.

1   7/10

Step-by-step explanation:

We started out with 4 1/5 scoops of oats, then the horse ate 2 1/2 of the scoops of oats. We need to subtract how much the horse ate from the original number of scoops of oats.

To do that, we need to find a common denominator. Both 5 and 2, our original denominators, will go into 10.  So now we have the common denominator, but we must do the same to the numerators.

2•1=2, therefore the original number of scoops is now 4 2/10

5•1=5, therefore the original number of scoops the horse ate is now 2 5/10

The only thing left to do now is to subtract:

4 2/10 - 2 5/10, we need to borrow from the whole number. Our new equation is: 3 12/10 - 2 5/10.

3 12/10 - 2 5/10 =  1  7/10

1  7/10 cannot be simplified, leaving your answer to be 1 7/10 buckets of oats left in his bucket.
