There are 15 girls in a sixth grade class. only 40% of the class are boys. how many are in the class?

hello :  in the class: 25

Step-by-step explanation:

60% represent 0.60 in  15 girls  

40% represent 0.40 in  x  boys

so : x = (15×0.40)/0.60 = 10  boys

in the class: 10 boys + 15 girls = 25

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
