Answer 2

Answer:

3 1/2 or 3.5

Step-by-step explanation:

We have to divide to see how many times her monday's distance was her tuesdays distance.

$6\frac{3}{10}\div \:1\frac{4}{5}$

$=\frac{63}{10}\div \frac{9}{5}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{63}{10}\times \frac{5}{9}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{63\times \:5}{10\times \:9}$

$=\frac{315}{10\times \:9}$

$=\frac{315}{90}$

$\mathrm{Cancel\:the\:common\:factor:}\:45$

$=\frac{7}{2}$

$=3\frac{1}{2}$

we can also be 3.5 in decimal form
