Best Answer

Given (3/8) + (2/5):

You can simplify the expression by first finding a common denominator - any one works.

The easiest way to do this is to multiply the denominators of each fraction.

8 * 5 = 40

And then multiply the numerators by the opposite denominator to keep each fraction equal.

(3*5)/40 + (2*8)/40 = 31/40

So there's your answer. Three eighths plus two fifths equals thirty-one fourthy-ths
