It was recently estimated that homes without children outnumber homes with children by about eight to seven. If there are 3870

homes in a county, how many of them are homes without children?

First you wanna add the proportions (8+7)
Then divide 3870 by 15. Which is from the 8+7
Then you times this number by 8, (258*8)
Then thats your answer (2064)
