Me ! asap! ! brainliest answer! there are 240 students in the seventh grade. the ratio of girls to boys is 7 to 5. what percent of the students are boys?

Lets find how many boys there are.

First we add the ratios:
7 + 5 = 12

Then we divide the total number of students by this:
240 / 12 = 20

Now to find out how many boys there are, we times this by the ratio of boys:
20 x 5 = 100

Finally we divide the number boys, by the total number of students. We then times this number 100 to change it from a decimal to a percentage.

100 / 240 = 0.41666 (Multiply this by 100 to get the percentage)
0.41666 x 100 = 41.67%

Yo yo yup because it’s so cool and awesome dude
