in Rosa's class there are 15 boys and 12 girls on Wednesday all the girls were present and 1/5 of the boys were absent how many students were in class that day

So, 1/5=3/15, so that means 3 boys were absent that day.

And add to my previous response, 15+12=27, and 27-3=….. So now you get it?

the 2a= 76(a0) n= wig (hours 80) 90(E.000000000000.1111.2)

i just dont get it

To find the total number of students in Rosa's class on Wednesday, we need to add the number of boys and girls together.

First, we know that there are 15 boys in the class. But on Wednesday, 1/5 of the boys were absent. To determine how many boys were absent, we need to calculate 1/5 of 15:

1/5 * 15 = 3

So, 3 boys were absent on Wednesday.

Next, we know that there are 12 girls in the class, and all of them were present on Wednesday.

To find the total number of students in class on Wednesday, we add the number of boys (12 - 3 = 9) and the number of girls:

9 boys + 12 girls = 21 students

Therefore, there were 21 students in Rosa's class on Wednesday.

So number present = the girls + (4/5) of the boys

= 12 +(4/5)(15)
= ...

What part did you find difficult?
