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 :)
