At a little league game, three fourths of the people in the stands were kids amd the rest were parents. If the ratio of dad to moms is 3:4, what percent of the people attending the game were moms? (Give answer to the nearest percent.)
number of people in stands --- x
number who were parents = (3/4)x)
of those 4/7 were moms
total moms = (3/4)(4/7)x = (3/7)x
percentage of moms = (3/7)x / x
= 3/7 = appr 43%
