Answer:
25,
8:5
4:3
Step-by-step explanation:
you have to model it as a system of equations.
first, we know there are a total of 65 children, boys and girls. so
we also know there are 15 more boys than girls so
now, we can plug the second equation into the first to get
so
if g = 25, b must = 40, because it is g+15.
the ratio will be 40 boys to 25 girls. 40:25 or 8:5 if you simplify.
if there are 5 more girls, g = 25+5 = 30, so the ratio is 40:30 or 4:3.
