The ratio of boys to girls in a class is 4:5 What fraction of the class are boys?
What fraction of the class are girls?

4/9 for boys and 5/9 for girls

explanation:

there are 4 boys and 5 girls

so there are nine in total

if there are four boys and 9 in total then the fraction would be 4/9

and if there are 5 girls and 9 in total then the fraction would be 5/9

hope this helps and it plays Mark brainliest :D

is this part of a question or something

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
