Nance is riding her bike to a friend’s house 4 and 1/2 miles away. She’s ridden 2 and 3/5 miles. How much farther does she need

<h2>Hello!</h2>

The answer is:

She still needs to ride

$1\frac{9}{10}miles$

From the statement, we know that Nance's friend is 4 1/2 miles away and she only has ridden 2 3/5 miles.

So, let be "x" the distance that she still need to ride to get to her friend's house.

The equation will be:

$TotalDistance=RiddenDistance+x$

Remember that:

$a\frac{b}{c}=a+\frac{b}{c}$

Also, if we need to add/substract fractions we must remember that:

$\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}$

If we need to switch fractions to mixed numbers, we need to:

- Perform the division

- Keep the whole number and make a fraction with the aproximated next whole number (remainder) as numerator, and the original denominator. We need to use the remainder to approximate to the next whole number.

$\frac{a}{b}=c.r$

Where:

$a=numerator\\b=denominator\\c=WholePart\\r=NextWholeNumber$

So,

$\frac{a}{b}=c\frac{r}{b}$

Then, substituting the given information into the equation, we have:

$4\frac{1}{2} =2\frac{3}{5} +x\\\\x=(4\frac{1}{2}) -(2\frac{3}{5})=4+\frac{1}{2}-2-\frac{3}{5}=2+\frac{1}{2}-\frac{3}{5}\\\\x=2+\frac{1}{2}-\frac{3}{5}=2+\frac{5-6}{10}=2-\frac{1}{10}\\\\x=2-\frac{1}{10}=\frac{20-1}{10}=\frac{19}{10}$
