Question

Hi. Could someone please help me help my son with his homework. TIA

Answer 1

If the question is how much Cody will jog to save ratio 4miles:3 miles
The ratio is $\frac{3}{4}$
We can just multiply 1 miles by ratio to see how much Cody will jog, so
$1* \frac{3}{4} =\frac{3}{4}$ miles 
The result is $\frac{3}{4}$ miles
