Answer 2

Answer:

15

Step-by-step explanation:

To subtract 2 1/2 - 1 3/5, first, you need a common denominator for the fractions, which is 10.

The subtraction becomes

2 5/10 - 1 6/10

Now you need to subtract 1 6/10 from 2 5/10.

Since the fraction part involves the subtraction 5/10 - 6/10, we need to borrow. You must change 2 5/10 to a mixed numeral with a larger numerator than 5, so you can subtract 6/210 from it.

Start with 2 5/10.

Borrow 1 from the 2. The 1 you borrow from 2 will be added to 5/10.

You think of the borrowed 1 as 10/10. Now you add 10/10 to 5/10.

2 5/10 becomes 1 15/10. Now that the fraction has a numerator grater than 6, you can do the subtraction.

2 5/10 - 1 6/10 =

= 1 15/10 - 1 6/10
