Question 122373
The new parking lot has spaces for 450 cars. The ratio of spaces for full-sized cars to compact cars is 11 to 4. How many spaces are for full-sized cars? How many spaces are for compact cars? 
:
Let x = no. of spaces for full size cars
then
(450-x) = no. of spaces for compact cars
:
"The ratio of spaces for full-sized cars to compact cars is 11 to 4."
{{{x/((450-x))}}} = {{{11/4}}}
:
You can cross multiply to solve this:
