At a summer camp there are 60 girls and 30 boys. Twenty percent of girls and 40% of boys passed the swimming test. What percent of the campers passed. Please show working.
0.2 * 60 = 12 girls passed
0.4 * 30 = 12 boys passed
24 / 90 = 0.2666 = 26.7%
Well, let's do the math and solve this problem step by step!
First, we need to find out how many girls passed the swimming test. We know that 20% of girls passed, and there are 60 girls in total, so we can calculate:
20% of 60 girls = (20/100) * 60 = 12 girls passed
Next, let's find out how many boys passed the swimming test. We know that 40% of boys passed, and there are 30 boys in total, so we can calculate:
40% of 30 boys = (40/100) * 30 = 12 boys passed
Now, we can sum up the number of successful boys and girls:
12 girls + 12 boys = 24 campers passed the swimming test
Finally, let's calculate the percentage of campers who passed. There are a total of 60 girls + 30 boys = 90 campers in total.
So, the percentage of campers who passed is:
(24/90) * 100 ≈ 26.7% of campers passed
Therefore, approximately 26.7% of the campers passed the swimming test.
To find the percentage of campers who passed the swimming test, we need to calculate the total number of campers who passed the test.
First, let's find the number of girls who passed the swimming test.
20% of 60 girls = (20/100) * 60 = 12 girls
Next, let's find the number of boys who passed the swimming test.
40% of 30 boys = (40/100) * 30 = 12 boys
Now, let's calculate the total number of campers who passed the swimming test.
12 girls + 12 boys = 24 campers
To find the percentage, we divide the number of campers who passed the test by the total number of campers and multiply by 100.
(24 / (60 + 30)) * 100 = (24 / 90) * 100 ≈ 26.7%
Therefore, approximately 26.7% of the campers passed the swimming test.
To determine the percentage of campers that passed, we need to calculate the total number of campers who passed the swimming test and then divide it by the total number of campers.
First, let's find the number of girls who passed the swimming test by multiplying the total number of girls (60) by the percentage of girls who passed (20% or 0.20):
Number of girls who passed = 60 * 0.20 = 12
Next, let's find the number of boys who passed the swimming test by multiplying the total number of boys (30) by the percentage of boys who passed (40% or 0.40):
Number of boys who passed = 30 * 0.40 = 12
Now, we can calculate the total number of campers who passed by adding the number of girls and boys who passed the swimming test:
Total number of campers who passed = Number of girls who passed + Number of boys who passed = 12 + 12 = 24
Finally, to find the percentage of campers who passed, we divide the total number of campers who passed (24) by the total number of campers (60 girls + 30 boys = 90):
Percentage of campers who passed = (Total number of campers who passed / Total number of campers) * 100%
= (24 / 90) * 100%
≈ 26.67%
Therefore, approximately 26.67% of the campers passed the swimming test.
