this seems to be two questions
1st
b + g = 30
b = g + 4
substitute to find solution
2nd
4 + 1 = 5
30 / 5 = 6
30 - 6 = 24
there are 24 of one
and 6 of the other
There are 30 students in the class.
There are 4 more boys than girls in the class. What do I do to solve this?
The ratio is 4:1? Then what do with the 30? I am very confused.
