Sagot :
Michelle walks 1/4 hour per day
In 1 week she walks in 7 days, then she walks:
[tex]\frac{1}{4}\cdot7=\frac{7}{4}\text{ hours per w}eek\text{ }[/tex]And in 9 weeks she walks:
[tex]\frac{7}{4}\cdot9=\frac{63}{4}=\frac{60+3}{4}=\frac{60}{4}+\frac{3}{4}=15\frac{3}{4}\text{ hours}[/tex]Sandra walks 2/4 hour per day
In 1 week she walks in 5 days, then she walks:
[tex]\frac{2}{4}\cdot5=\frac{10}{4}=\frac{5}{2}\text{ hours per w}eek[/tex]And in 9 weeks she walks:
[tex]\frac{5}{2}\cdot9=\frac{45}{2}=\frac{44+1}{2}=\frac{44}{2}+\frac{1}{2}=22\frac{1}{2}\text{ hours}[/tex]Therefore, Sandra walked more.
[tex]\frac{45}{2}-\frac{63}{4}=\frac{45\cdot2-63\cdot1}{4}=\frac{90-63}{4}=\frac{27}{4}=\frac{24+3}{4}=6\frac{3}{4}[/tex]Sandra walked 6 3/4 more hours than Michelle.
