Question

8/9 + (-3/4)
I'm stuck on thisss

Answer 1

5/36

Explanation:

find the the common denominator for 9 and 4

Answer 2

Answer: 5/36

First, find the LCD of both the denominators (in this case, 9 and 4).

LCD = 36

Then, multiply each fraction by the number that would give you a denominator of the LCD that you found earlier (in this case, 36).

(8/9) · 4 + (-3/4) · 9 = (32/36) + (-27/36)

Now, you just have to add the numerators because the fractions have the same denominator.

(32/36) + (-27/36) = 5/36

∴ it equals 5/36.
