Your friend has a bag of 20 marbles. Seven

are blue, four are red, two are green, and

three are yellow. If the rest are white, what

percent of the marbles are white?

20%

Step-by-step explanation:

First, I added them up. From the things we know, blue, red, green, yellow combined equals 16 marbles. 20-16 equals 4. So there are 4 white marbles. 4/20 times 5 equals 20/100. So the percent of the marbles that are white is 20%.
