Step-by-step explanation:

Each of these problems are asking for a percent. The easy way to get a percent is to do this:

If the percent is in the 1's place (a number like 7%), take the number from the thing your getting the percent from and divide is by 100. So if you had the problem 5% of 50, you're then going to have 0.5

Then, with that number that you have, multiply is by the percent. So with the problem I have shown earlier, you will get 2.5, which is the answers.

If you have a percent that is in the ten's place, then divide by 10and then divide the percentage by 10 THEN multiply.

When you have a percent like 36% or 97% ( a percent with both place values), separate the two place values, do them individually, then add them together.
