Question

What
should be added to -7/8to get 4/9​

Answer 1

Answer:

let the number that should be added to 1/4 to get 4/9 be x. hence, 7/36 must be added to 1/4 to get 4/9.

Answer 2

Answer:

Let x be the number added

-7/8 + X = 4/9

.

X = 4/9 + 7/8

LCM of 9,8 = 72

4/9 *72/72 + 7/8 * 72 /72

= 32 / 72 + 63/ 72

= 95/72

X = 95 /72.
