Y. You Be the Teacher Your cousin says you have to regroup every time you subtract from a number that has a zero. Is yo cousin correct? Explain. As part of an annual hundraiser to help raise money for cancer research, Rachel joined a walkathon. The track she walked on was 770 yd long. Rachel walked 16 laps. Her sponsors agreed to donate an amount of money for each mile she walked. How many miles did she walk? First fill in the blanks on the left side of the equation using three of the ratios shown. Then write your answer on the right side of the equation. Ratios: \( \frac{3 \mathrm{ft}}{1 \mathrm{yd}} \) \( \frac{1 \mathrm{yd}}{3 \mathrm{fl}} \) \( \frac{770 \mathrm{yd}}{1 \text { lap }} \) \( \frac{1 \text { lap }}{770 \mathrm{yd}} \) \( \frac{5280 \mathrm{ft}}{1 \mathrm{mi}} \) \( \frac{1 \mathrm{mi}}{5280 \mathrm{ft}} \) \( f \) yd mi \( \square \) in 15 \( \frac{16 \mathrm{laps}}{1} \times \) \( \square \) x \( \times \) \( \square \) miles (a) Write \( 709 \% \) as a decimal. (b) Write 0.008 as a percentage. (a) \( 709 \%=\square \) (b) \( 0.008=\square \% \) A little bear had 75 peaches. Each day, he kept a fraction of his peaches, gave the rest away, and then ate one.
