Answer 2

Answer: 2 and 5/6

Explanation: To subtract mixed numbers, first subtract the fractions.

Notice here however that we have 2/6 - 3/6 which will gives us a negative fraction. Since this will cause us a lot of trouble, instead, let's rewrite the the first mixed number.

We can do this by thinking of 10 and 2/6 as 9 + 1 and 2/6 or as 9 + 8/6 by changing 1 and 1/6 into an improper fraction.

So 10 and 2/6 can be written as 9 and 8/6.

So we have 9 and 8/6 - 7 and 3/6.

Now subtract the fractions.

So we have 8/6 - 3/6 which is 5/6.

Then subtract the whole numbers. 9 - 7 is 2

2 and 5/6 is in lowest terms so 10 and 2/6 - 7 and 3/6 is 2 and 5/6.
