To find the number that should be added to -7/8 to get 4/9, we can set up the equation:
-7/8 + x = 4/9
To solve for x, we need to eliminate the denominators by finding a common denominator. In this case, the least common multiple of 8 and 9 is 72.
Converting the fractions to have a denominator of 72:
(-7/8)(9/9) + x = (4/9)(8/8)
-63/72 + x = 32/72
Now, we can add -63/72 to both sides of the equation to isolate x:
-63/72 + x + 63/72 = 32/72 + 63/72
x = 95/72
Therefore, the number that should be added to -7/8 to get 4/9 is 95/72.
-7/8 + x = 4/9
To solve for x, we need to eliminate the denominators by finding a common denominator. In this case, the least common multiple of 8 and 9 is 72.

Now, we can add -63/72 to both sides of the equation to isolate x:
-63/72 + x + 63/72 = 32/72 + 63/72
x = 95/72
Therefore, the number that should be added to -7/8 to get 4/9 is 95/72.
