C ( To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed. )
The first one is 9/16 you have to make 54 and 96 a fraction such as 54/96 then simplify
the second one is 1/5 you have to make 4 and 20 a fraction like this 4/20 then simplify
hope this helps!!

5. 9t
7. -22+3b
Step-by-step explanation:
1. 5g-2(g-7)
5g-2g+14
3g+14.
2. 32n-3(n-7)
32n-3n+21
29n+21
3. 12p-2(p-4)
12p-2p+8
10p+8
4. 4(3e-2)-3e
12e-8-3e
5. -5t(t-3)
-6t+15t
9t
7. -4(3-b) +2(3b +2)-7(b+2)
-12+4b+6b+4-7b-14
-22+3b
