First, find the LCD (Lowest Common Denominator)
7/8 - 2/5 =19/40
The lowest number that 8 and 5 will only divide into evenly is 40.
40/8=5 & 40/5=8
Second, multiply the top number by the same as the bottom number.
8*5=40 so 7*5=35 -> 7/8 = 35/40
Third, do the same for the other fraction in the equation.
5*8=40 so 2*8=16 -> 2/5 = 16/40
Fourth, now just subtract the top numbers.
35 16 19
---- - ---- = ---- is the solution.
40 40 40
