17. There should be 18, but one has gone to the toilet.
It is not opssible to give a sensible answer to this question. 46+58 = 104. So if the class has 46% girls and 58% boys then the class has 4% who are simultaneously girls and boys.
80 = 100% 8 = 10% 32 = 40% 80 - 32 = 48
THIS IS NOT A ANSWER THIS IS JUST THE WORD PROBLEM! There are 340 students in Blueprint Middle School, 40% are boys. How many students are girls in Blueprint?

A percent means--per 100. Let's say we know there is a groulp of 35 students of which 7 are girls. Q. What is the percent of girls in the group? A. First we look at the number of girls divided by the total number of students. This will give us a decimal number. In this case, O.2 To get the percent of girls, we convert this decimal to percent or per 100 by both multiplying and dividing by 100. We can do this without changing the value of 0.2 since 100/100=1. We just change the units. (In this case though we just don't do the division.) So this turns out to be 20/100 eg 20 per 100 or 20 percent.
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11

There would be 6 boy students and 18 girl students in the class.
