Answer 1

`\large\boxed{(26)/(35)}`

Explanation:

`2(1)/(7)-1(2)/(5)\\\\\text{Find LCD}=7\cdot5=35\\\\2(1)/(7)=2(1\cdot5)/(7\cdot5)=2(5)/(35)\\\\1(2)/(5)=1(2\cdot7)/(5\cdot7)=1(14)/(35)\\\\\\2(1)/(7)-1(2)/(5)=2(5)/(35)-1(14)/(35)=1(35+5)/(35)-1(14)/(35)=1(40)/(35)-1(14)/(35)=(40-14)/(35)=(26)/(35)`
