Question

if 13/4 equal 50 miles how many miles equal 7 inches

Answer 1

I would change the improper fraction to a decimal. So 13/4 = 3.25

Next I would write the problem as a proportion. So it would look like this:

\[\frac{ 3.25 inches }{ 50miles}=\frac{ 7 inches }{ ? miles}\]

Cross multiply 7 times 50, which gives us 350 And divide by the other number.(3.25)

350/3.25=107.69

So the ? = 107.69 If we round to the nearest mile, the answer is 108 miles.
