Answer :

Answer: 2 3/5 - 1 15/20 = 1 17/20

Step-by-step explanation:

To subtract mixed numbers, you first need to convert them into improper fractions and then perform the subtraction.

Let's convert the mixed numbers into improper fractions:

2 3/5can be written as 2+ 3/5 =10/5+ 3/5 = 10 + 3/5 = 13/5

15/20 can be written as 1 + 5/20 = 20/20 + 15/20 = 20 + 15/20 = 35/20

Now, we subtract the fractions:

13/5 - 35/20

To subtract these fractions, we need to find a common denominator, which is 20:

13/5 = 13 x 4/5 x 4 = 52/20

Now, we can subtract:

52/20 - 35/20 = 52 - 35/20 = 17/20

So, 2 3/5 - 1 15/20 = 1 17/20
