Flashcard 8 - Mathematics Flashcard Set for the TABE Test

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

or

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

\(\frac{75}{N} = \frac{45}{100}\)
Cross-multiply to find
\(75 \cdot 100 = 45 \cdot N\)
\(7500 = 45N\)
Divide both sides by 45.
\(N = 166.67\)
