If 2/5 of the students in the class are girls. what fraction are the boys. If the class has 35 students, how many boys are in the class?

If 2/5 of the students in the class are girls, what fraction are the boys?

[] Let's say the whole class is equal to 5/5.

[] If there are only girls and boys in the class, then we can do the math 5/5 - 2/5 = 3/5 to find 3/5 of the class is boys

-> 3/5 of the class is boys

If the class has 35 students, how many boys are in the class?

[] With the second part of this problem, we are given more information.

[] Our whole, 5/5 before, is equal to 35. We can multiply 3/5 (boys in the class) by our whole, 35, for our answer.

[] This gives us 21 boys in the class. We can test this by seeing that 3/5 = 21/35, so this solution makes sense.

-> There are 21 boys in the class

Have a nice day!

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
