I am supposed to use the percent porportion to solve each problem.

The problem is:
What is 70% of 50 :?:

I am having a lot of trouble with this and i need to know how to work the problem i have set up 70 over x and 100 over 50 is this the right process to solve the proportion?

I really need help with this tonight :!: :!: :!:
 
Using proportions, you are correct:

70/x = 100/50

cross multiply

100x = 3500

divide both sides by 100 to get your answer.

Not percent. It is simply 35 :)

Because 70% of 50, is 35. Just like 50% of 100, is 50.
OOOOKKKK!,now i get it...thanks i have a test tomorrow over this! and now i can do it without sitting there for like an hour frusterated! thank you soooo much!!! :lol: :D :)
 
That applies to any similar calculations, RM; just multiply, then divide by 100;
like, 37% of 500 = 37 * 500 = 18500; divide by 100: 185
