The ratio of Isabella's money to Shane is 3:11 If she has $33, how much do they have together?

The ratio of Isabella’s money to Shane’s money is 3:11 Isabella has $33.    We can make a proportion to solve for how much money Shane has.    A proportion is two ratios that are set equal to each other.   Let’s call Shane’s money ‘S’    We get this proportion:   3/11 = 33/x    If we cross multiply we get:    (33) * (11) = (3) * (x)    Simplifying it, we get: 363 = (3) * (x)    Divide both sides by 3, we get: x = 121    However, the question asks how much money they have together.  Isabella + Shane = Total 33 + 121 = $154    They have $154 together.
