A bag contains 18
red balls and
4
blue.

What percentage of balls are red?

81% of the balls are red

Step-by-step explanation:

If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball

18 red + 4 blue = 22 balls  part (a)

18/22 = 9/11   part (b) simplify

9/11 * 100     part (c) multiply the fraction by a hundred to get the percentage

81.81 ~ 81%  part (d) solve

81 9/11%

Step-by-step explanation:

First add the number of red and blue balls together. 18 + 4 = 22

What is the number of red balls? It’s 18

We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.

Therefore, the answer is 81 9/11%.
