Answer:

1 26/35

Step-by-step explanation:

Before subtracting, you must find the common denominator.

The lowest number 7 and 5 can both make is 35.

Now, we must convert the fractions.

15/7 = 75/35

2/5= 14/35

Now because we have the same denominator, we can subtract.

75/35

-

14/35= 61/35.

61/35= 1 26/35.

Now you can simplify your answer. 1 26/35 cannot be simplified so that's your answer.
