If 80% of M is equal to 50% of N and N ≠ 0 what is N/M equal to?

M/N=5/8  or 62.5%

Step-by-step explanation:

when turning the word problem to equation...

since you have the value of M in terms of N you should substitute M by 5N/8.

if you want it as a percent just multiply 5/8 by 100%.

=62.5%

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
