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.

Answer:
B. 20
Step-by-step explanation:
First, 20% of 20 is 4.
36 decreased by 4 (36-4) is 32.
The equation is N (160%)=32 or 1.6n=32
160% because it was already 100%, and its increased by 60% (100+60)
Divide both sides by 1.6.
You get n=20
I hope this helps!
