Answer:
6/35
Step-by-step explanation:
TO start you have to get a common denominator.
The lowest common multiple is 35, which just requires you to multiply the bottom two numbers to their fractions.
so you would do 3/5 times 7 on the top and bottom to get 21/35
then on the other one you would take 2/7 times 5 to get 15/35
you now have 21/35-15/25 or essentially 21-15 which is 6 and keep the denominator
you come out with 6/35
