In a church, the ratio of adults to children is 7 to 11.
If there are 144 people in the church, how many children are there?
:
let x = the multiplier
then
7x = number of adult
and
11x = number of children
the total equation
7x + 11x = 144
18x = 144
x = 144/18
x = 8 is the multiplier
therefore
8(11) = 88 children
:
:
Check this; 8(7) = 56 are adults
88 + 56 = 144
