So in this problem, we're told that the ratio of the number of boys to the number of girls in the chess club is six to five.
00:06
But we're also told that there's three more boys than girls.
00:10
We want to figure out how many total members are in the club.
00:13
So first, it would be helpful if we could find even number of the boys or the number of the girls.
00:17
Well, let's use the fact that there's three more boys than there are girls.
00:23
So what i'm going to do is i'm going to let x equal the number of girls.
00:28
So if there's three more boys than girls, then x plus three represents the number of boys.
00:35
So now what we're going to do is set up a proportion using our ratio.
00:38
So remember, we were at first told the ratio boys to girls was six to five.
00:43
Keep in mind, boys is in the numerator.
00:46
So we just wrote an expression for the number of boys.
00:49
It's x plus three...
