Asked by Javonte

Tom and Jasper have the same percentage of blue marbles in their bags of marbles. Tom has 5 blue marbles and 20 total marbles. Jasper has 12 blue marbles. How many of Jasper's marbles are not blue?

Can someone show me how to solve this problem?
Answered by Morgan
well tom's bag is 25% blue (5/20). Since Jasper has 12 blue you would have to multiply by four to get the total number of marbles (48). Finally you would subtract the number of blues from Japer's total (48-12=36).

Can you please explain how you got 4 to multiply by 12(12*4)?

Here is another way of looking at Morgan's solution.
Morgan found the percentage to be 25% or 1/4 of the marbes are blue.

So 1/4 of Jasper's marbles must be blue , it said they have the same percentage of blue marbles.
Let the total of Jasper's marbles be x

then (1/4)x = 12
x = 4(12) = 48
So Jasper has 48 marbles, of which 12 are blue
So 36 are non-blue
