Each marble bag sold by Soo's Marble Company contains 3 orange marbles for every 4 purple marbles. If a bag has 36 purple marbles, how many orange marbles does it contain?

Answer 1

we can set up a proportion here:
\[\huge \frac{ orange }{ purple }\]

we will always have to maintain that order in order to get the answer.

what is also given is that the marbles are sold in a particular order: 3 orange marbles, for EVERY 4 purple marbles
\[\large \frac{ 3orange}{ 4 purple }\]

we know that there is 36 purple marbles, but we need to find the number of orange marbles.
\[\large \frac{ 3orange }{ 4purple } = \frac{ x }{ 36 purple }\]
as you can see, x represents the unknown number of orange marbles

to solve for x, you need to "cross multiply"
\[\large 36 \times 3 = 4x \]

Answer 2

solve for x
