1. Use a Giant One to change each of the following fractions to a number with a denominator of 100. Then write each portion as a percent. Homework Help ✎

200 times what is 100? This number will be the denominator, or the bottom of the fraction, in your Giant One.
Remember, in a Giant One the numerator, or the number on top, and the denominator will be the same so that the fraction is equal to one.

$\text{Here\ your\ Giant\ One\ should\ be\: \frac{0.5}{0.5}.\ }$

$\text{Can\ you\ multiply\\ \frac{85}{200}\ and\ \frac{0.5}{0.5}\\ to\ get\ a\ }$

$\text{new\ fraction\\ with\ a\ denominator\ of\ 100?}$

$\frac{85}{200}=\frac{42.5}{100}$
