You have to first get the eighths and the ninths to the same fraction. Multiply 8 by 9 = 64ths. Then cross - multiply the top numbers by the opposite dividend. Ie. 7x9(ths) and 4x8(ths) and add them together = 63+32 = 95/64ths = 1 31/64ths
Eight and seven eighths.
It is seven ninths.
The sum is 8 1/2 or 8.5

1/2+3/8=7/8 -lover of math geeks ;) the common denominator is eight, so one half is converted into four eights. Then, three eighths plus four eighths is seven eighthts, so your answer is seven eighths. - A math geek
4/9 + 7/8 = 95/72
It is 8 5/8.
4/9 plus 7/15 = 41/45 in its simplest form
