Question

3) There are 16 cups in a gallon. The equation c=16g gives the number of cups in terms of the number of gallons. Write another equation for this situation, giving the number of gallons in terms of the number of cups:

Answer 1

We know the equation

$c=16g$

gives the number of cups if we know the numbe rog gallons.

If we want an equation that gives the number of gallons if we know the number of cups we just have to solve hte equation for g, that is:

$g=\frac{c}{16}$

Therefore, the equation we are looking for is:

$g=\frac{c}{16}$
