number of children #=80#

So, we have a ratio of 13 adults : 5 children

This means that for every #18 (13+5)# people in total we have 5 children.

This can be displayed Algebraically as,

#288/18=x/5# where x is the number of children

#x=80#

Another way of doing this question is to find what one unit is,

#"number of adults"+"number of children"=288#

#13x+5x=288#

#18x=288#

#x=16#

and then multiply by ratio.

number of children = #5x#

#=5*16#

#=80#
