Create an expression equal to 6/5 what you have to work with: 1/16, (7/10, -, 5/8), ÷

Alright, so by finding a common denominator (with a bit of guess and check) we get 1/16=5/80 (since 80/16=5 and 5*1=5), 7/10=56/80, and 5/8=50/80. 
In addition, 6/5=96/80. To get this, we'd want 6 as the numerator and 5 as the denominator. Noting that we have parenthesis (meaning that (7/10 has to start with the parenthesis and 5/8) has to end it), we can also notice that (56-50)/80=6/80 and since 1/16=5/80, we can divide them to get (6/80)/(5/80)=
(6*80)/(5*80)=6/5

Subtracting is the opposite of adding
