Answer :
6/7-2/3
Make sure they have the same denominators which means looking for the GCF
So the GCF is 21 in this case
6/7= 18/21
2/3= 14/21
18/21 - 14/21= 4/21
The answer is 4/21
THE ANSWER IS 4/21 you first find the common denominator which is 21, 7x3=21 so 6/7 becomes 18/21 and 2/3 becomes 14/21. You than subtract 18/21 - minus 14/21 which equals to 4/21
