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.
