Victor's breakfast cereal has fourteen point four mg of Iron, which is eighteen percent of the Recommended Daily Allowance (RDA) of Iron. What is the RDA of Iron?

Victor's breakfast cereal has eighteen mg of Iron. What percentage of the Recommended Daily Allowance (RDA) of iron?

Answer 1

This is a simple algebra problem. 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%
