Question

There are 20 balls in a bag. Ten of the balls are red, 4 are green, and the rest are yellow. Which ratio represents the number of yellow balls to red balls?

a. 1/5
b. 3/10
c. 2/5
d. 3/5

Answer 1

The ratio that represents the number of yellow balls to red balls is 3/10 (Option b).

Step-by-step explanation:

The ratio that represents the number of yellow balls to red balls is 3/10 (Option b).

To find this ratio, we need to determine the number of yellow balls and the number of red balls in the bag. Given that there are 20 balls in total, and 10 of them are red and 4 are green, we can conclude that the remaining balls must be yellow.

Therefore, the number of yellow balls is 20 - 10 (red balls) - 4 (green balls) = 6.

The ratio of yellow balls to red balls is 6/10, which can be simplified to 3/5.
