Answer:

Step-by-step explanation: honestly don’t know

You can just subtract them seperatly like this:
20-12=8
2/5-3/5= -1/5
Since its negative, you have to take 1 off of the final answer and put 4/5 so the answer is 7 4/5

Another way is making it a decimal
12 3/5= 12.6
20 2/5= 20.4

20.4-12.6= 7.8
7.8=7 4/5

For the first scenario, you’re looking at a compound interest problem. You’re given all the information you need, so just input it into the compound interest equation.

A = P(1 + r/n)^nt

P is your principal, aka starting amount. That’s the 12000 people you start with.

R is your rate of interest, aka how much your principal is expanding by. That’s the 5% growth rate each year, or 0.05.

N is the number of times your principal grows each year. That’s only once here.

T is however long the change lasts. In this scenario, its from 2006 to 2020, so 14 years.

Input all this in and solve for A, which is your total amount.

A = 12,000(1 x 0.05/1)^(1 x 14) = 23,759.18

Since I doubt you can have 1/5 of a person, you round this down to 23,759, which is your answer.

I’d like to help with your second problem, but it’s cut off on the edge of the image, I can’t see all the numbers.
