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?
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).
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
Can you Please explain another way.
Can you please explain how you got 4 to multiply by 12(12*4)?
To solve this problem, we need to find the percentage of blue marbles in both Tom's and Jasper's bags. Then, we can use the information given to find the number of marbles that are not blue in Jasper's bag.
1. Find the percentage of blue marbles in Tom's bag:
Tom has 5 blue marbles out of 20 total marbles.
So, the percentage of blue marbles in Tom's bag is (5/20) * 100 = 25%.
2. Since Jasper and Tom have the same percentage of blue marbles, Jasper also has 25% blue marbles.
3. Find the number of blue marbles in Jasper's bag:
We know that Jasper has 12 blue marbles.
Since the percentage of blue marbles in Jasper's bag is 25%, we can set up the following equation:
(12/total number of marbles in Jasper's bag) = 25/100
To find the total number of marbles in Jasper's bag, we need to rearrange the equation:
total number of marbles in Jasper's bag = (12 * 100) / 25 = 48
4. Calculate the number of marbles that are not blue in Jasper's bag:
We know that Jasper has a total of 48 marbles and 12 of them are blue.
So, the number of marbles that are not blue in Jasper's bag is 48 - 12 = 36.
Therefore, there are 36 marbles in Jasper's bag that are not blue.
