If Myron receives votes from his class of students, what percentage of the votes does he receive?
A
multiplied by equals
B
multiplied by equals
C
multiplied by equals
D
multiplied by equals
Verified step by step guidance1
Identify the total number of votes and the number of votes Myron received. Here, the total votes are 25 and Myron received 10 votes.
Set up the fraction representing the part of the votes Myron received out of the total votes: \(\frac{10}{25}\).
To convert this fraction to a percentage, multiply the fraction by 100: \(\frac{10}{25} \times 100\).
Simplify the fraction \(\frac{10}{25}\) by dividing numerator and denominator by their greatest common divisor, which is 5, resulting in \(\frac{2}{5}\).
Multiply the simplified fraction by 100 to find the percentage: \(\frac{2}{5} \times 100\).
