Answer 1

Can you reword this question please?

Answer 2

\( 7 \dfrac{1}{2}\)

and \( 1 \dfrac{1}{2}\)

right?

Answer 3

If so, all you need to do is divide

First change \( 7 \dfrac{1}{2}\) into an improper fraction like this

Answer 4

Can you do the same thing for \( 1 \dfrac{1}{2}\) ?

Answer 5

And then

so every day he's running 1 1/2 miles
and how many days will it take to run 7 1/2 miles

so all you have to do is divide

you need to use the improper fractions that you got earlier so 7 1/2 would be 15/2

and what do you get for 1 1/2 ?

so you have to divide 15/2 divided by whatever 1 1/2 is as an improper fraction

and this is the formula for dividing fractions

\( \dfrac{a}{b} \div \dfrac{c}{d} ~~~= ~~~\dfrac{a}{b} \times \dfrac{d}{c} ~~~= ~~~\dfrac{a\times d}{b \times c}\)
