Subtract. Write the answer in simplest form.

1) 3/7-4/5=10/35-28/35
This is the part that I got too and I don't know if I did it correctly or not. Can you please tell me how to do this or show me.

well, the idea is right, but

3/7 = 15/35

Then, do just what you did with the previous problem:

15/35 - 38/35 = -23/35

Plus, you misspelled "to"
I meant to put 1 and 3/7-4/5
That is what confuse me.
oh, well,

1 3/7 = 1+3/7 = 7/7 + 3/7 = 10/7
