Answer 2

Answer: 105 preschoolers are boys

The first thing we must do is add up our total to get a starting fraction. 3+4 is 7. Which means 3/7 of our students are boy and 4/7 of our students are girls.

Next we must multiply our total students "245" into the number of boys and girls.

3/7 x 245 is 105. 4/7 x 245 is 140.

105+140 is 245, which means our numbers are correct.

And finally that leads us with our answer.

105 of the students are boys.

I hope this helped & Good Luck <3!!
