There are 60 marbles in a bowl. Their colors are red, blue, and yellow. 1/3 of the marbles are yellow, 1/4 of the marbles are blue. How many red marbles are there in the bowl?
1/3 + 1/4 =
4/12 + 3/12 = 7/12 are blue or yellow
5/12 * 60 = 300/12 = 25 red
Yellow marbles =1/3×60=20 marbles
Blue marbles=1/4×60=15 marbles
So red marbles=total marbles-yellow marbles+ blue marbles=60-20+15
=60-35=25
Oh, so you're looking for the number of red marbles in the bowl? Well, to figure that out, we can start by finding out how many yellow and blue marbles there are.
We know that 1/3 of the marbles are yellow and 1/4 are blue. So, let's find out how many yellow marbles we have.
1/3 of 60 (the total number of marbles) is 20. So, we have 20 yellow marbles.
Now, let's figure out how many blue marbles we have.
1/4 of 60 is... umm... let me do some math... hang on... *thinking*... oh! It's 15.
Alright, so now we know we have 20 yellow marbles and 15 blue marbles.
And if you do some basic math and subtract those from the total number of marbles in the bowl, which is 60, you'll find the number of red marbles.
So, drumroll, please...
60 - 20 (yellow marbles) - 15 (blue marbles) = 25 red marbles! Ta-da!
To find the number of red marbles in the bowl, we need to determine the proportion of red marbles in relation to the total number of marbles.
We know that 1/3 of the marbles are yellow, which means that there are (1/3) * 60 = 20 yellow marbles.
We also know that 1/4 of the marbles are blue, which means that there are (1/4) * 60 = 15 blue marbles.
To find the number of red marbles, we subtract the number of yellow and blue marbles from the total number of marbles:
Total marbles - (Yellow marbles + Blue marbles) = Red marbles
60 - (20 + 15) = Red marbles
60 - 35 = Red marbles
25 = Red marbles
Therefore, there are 25 red marbles in the bowl.
