SOmeone help me 50 boys and 30 girls participated in a contest. 20% of the boys and 30% of the girls received prizes. What percentage of the contestants received prizes?

Boys= % of =

Girls= ___% of =

Total of contestants received prizes =

Total number of contestants participated=

To find the percentage:

Fraction (number of contestants received prizes to total number of contestants) x 100% = %

Boys= 20% of 50= 10

Girls= 30% of 30= 9

Total number of contestants received prizes= 19

Total number of contestants participated= 80

To find the percentage:

Fraction (number of contestants received prizes to total number of contestants) x 100% = 23.75%

Hope this helps, please mark Brainliest if I'm correct (I am 99.9% sure I'm correct, btw). Have a good day

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
