Answer:
126 children.
Step-by-step explanation:
Since this is fifth grade work, let's start by saying that the smallest number of children would be 7 (because 4/7 of them are boys, and that would be four boys--no fractions allowed!).
What is it's 4 boys & 3 girls? Then the number of boys would not be 18 more than the number of girls.
So let's try 14 children...8 boys, 6 girls...but difference in boy count and girl count is only two.
I guess we'll have to jump ahead...let's try 18 times 7, or 126 as total--4/7 of that is 72 boys, and 3/7 of that is 54 girls.
