on earth day 40 people volunteer to work at the city park cleanup. 10 of the 40 volunteers are high school students the coordinator wants to know what percent of the volunteers are in high school.
write a fraction to show the number of high school students out of the total number of volunteers
10 high school students out of 40 total volunteers = 10/40
To find the percentage, we divide the number of high school students by the total number of volunteers and then multiply by 100:
(10/40) * 100 = 25%
Therefore, 25% of the volunteers are in high school.
complete the equivalent fraction to show the number of high school students for every 4 volunteers
To find the equivalent fraction showing the number of high school students for every 4 volunteers, we need to simplify the fraction 10/40 by dividing both the numerator and denominator by their greatest common factor, which is 10.
(10 ÷ 10) / (40 ÷ 10) = 1/4
Therefore, for every 4 volunteers, there is 1 high school student.
as a part of his science experiment, ethan recorded the number of days it rained in april. over the 30 days it rained 15 days ethan wants to know what percent of the days in april it rained
write a fraction to show the number of days it rained out of the number of days in april
?/?
Number of days it rained in April: 15
Total number of days in April: 30
Fraction showing the number of days it rained out of the number of days in April:
15/30
This fraction represents the number of days it rained out of the total number of days in April.
complete the equivalent fraction to show the number of days it rained for every 2 days in april
15/30 = ?/2
To find the equivalent fraction showing the number of days it rained for every 2 days in April, we need to simplify the fraction 15/30 by dividing both the numerator and denominator by their greatest common factor, which is 15.
(15 ÷ 15) / (30 ÷ 15) = 1/2
Therefore, for every 2 days in April, it rained 1 day.
what percent of the days did it rain in april?
percent: ?%
To find the percentage of the days it rained in April, we can use the fraction 15/30 calculated earlier:
15/30 = 0.5
To convert the fraction to a percentage, we multiply by 100:
0.5 * 100 = 50%
Therefore, 50% of the days in April, it rained.
