<u>Let's set up some variables</u>:
- b: # of boys
- g: # of girls
<u>Let's set up some equations based on the informative given</u>:
- boys to girls ratio ⇒ 1: 12
(M<em>athematical form)</em> g = 12b
(<em>Mathematical form) </em>g = b + 77
<u>Let's put the equation together</u>:
g = 12b -- equation 1
g = b + 77 -- equation 2
(equation 2)'s value of g into (equation 1)
12b = b + 77
11b = 77
b = 7
There are 7 boys.
<u>Answer: 7 boys</u>
