Answer 3

?

Answer 4

First off, all percentages are to be plugged into the formula as their decimal equivalents. For example 18% equals .18. This is because all decimal equivalents are multiplied by 100 to get the percent equivalent. The simple formula is:

Full amount x (%) = Partial amount

You can plug the values into this formula and solve using basic algebra.

For example, your first problem is solved as follows:


Full amount x (%) = Partial amount
18 mg x (%) = 14.4 mg
% = 14.4 mg / 18 mg
% = 0.8 = 80%
