Flashcard 14 - Mathematics Flashcard Set for the HESI Exam

In word problems, these equations are often useful:

\[\frac{\text{is}}{\text{of}} = \frac{\text{percent}}{100}\]

or

\[\frac{\text{part}}{\text{whole}} = \frac{\text{percent}}{100}\]

Plug in the known values and solve for the unknown.

”\(5\) is what percentage of \(12\)” becomes:

\[\frac{5}{12} = \frac{\text{percent}}{100}\]

Cross multiply to solve.
