The ratio of boys to girls in Mrs. Ronilo's math class is 3 to 1. What PERCENT of the class is girls?
Out of every 4 students, 3 are boys and 1 is a girl.
25% are girls.
girls = X.
boys = 3x.
x/(x+3x) * 100% = x/4x * 100% = 1/4 * 100% = 25% are girls.
25%
To find out what percent of the class is girls, we need to first determine the total number of students in Mrs. Ronilo's math class.
Let's assume that there are 3 boys for every 1 girl. This means that for every 4 students in the class, 3 are boys and 1 is a girl.
To determine the percent of girls in the class, we need to divide the number of girls by the total number of students and then multiply by 100.
Since the ratio of boys to girls is 3:1, we can also say that for every 4 students, only 1 is a girl.
Therefore, the percentage of girls in the class would be (1/4) *100 = 25%.
So, 25% of the class is girls.
