so first we should make the denominators the same so find a multiple that 5 and 8 share: they share a multiple of 40, so whatever you do to the denominator you do to the numerator. So the equation should now look like 16/40+15/40 and the answer is 31/40!!
a simple way to do away with denominators, is we can simply multiply both sides by the LCD, in this case the LCD is 3, so let's multiply both sides by 3.
