I cannot figure this question out

uysha [10]

Answer:

1/12

Step-by-step explanation:

you need to make sure that they have a common denominator before doing anything.

Find the lowest common multiple (lcm), which would be 12 (3 x 4 = 12)

So then, put 12 as both denominators, and subtract.

7/12 - 9/12 is equal to 28/12 - 27/12, because 3 miltiplied by 4 equals 12, therefore you mutiply the 7 by the 4, and 4 miltiplied by 3 equals 12, therefore you multiply the 9 by the 3.

Sorry if this is confusing, i tried explaining as best i could! Hope this helped!
