Answer 1

I was gonna explain it but she did really good haha

Answer 2

Answer:

Huh, the answer option doesn't exist. The answer is 7.5 You can double check my answer by multiplying 7.5*4 because 25% is 1/4th of 100%.

Step-by-step explanation:

Use cross multiplication. I've heard it being called butterfly multiplication. I'll try to represent it as best as I can.

x           25

----   =  --------

30         100

You multiply 30 by 25 and x by 100

x*100=30*25

Then solve for x

x*100=750

x=750/100

x=7.5

Hope this helps :)
