In order to find out how many of the marbles are red and also have stripes we just follow this route:
We first find the ⅔ of the entire box, and then we will find the ¾ of the result that we got. That way we can find what we need.
Lets find first how many of the marbles are red.
So ⅔ of 48 marbles = ⅔*48
Multiply the numerator and the number together, and the result divide it with the denominator.
(2*48)/3 = 96/3
=32 red marbles
Out of these 32 red marbles, only ¾ of them are striped.
So we have ¾ of 32=¾*32
Multiply the number and the denominator together, and the in the end divide it by the denominator.
(3*32)/4 = 96/4
=24 of the marbles are red and striped.
