Question

I have 1/2-1/7 and3/5-1/2

Answer 1

1/2 - 1/7 = 7/14 - 2/14 = 5/14
3/5 - 1/2 = 6/10 - 5/10 = 1/10

Answer 2

`(1)/(2)-(1)/(7)=\ \ \ | make\ common \denominator\\\\ (7)/(14)-(2)/(14)=(7-2)/(14)=(5)/(14)\\\\ (3)/(5)-(1)/(2)= \ \ \ | make\ common \denominator\\\\ (6)/(10)-(5)/(10)=(1)/(10)`
