At a Little League game, three fourths of the people in the stands were kids and the rest were parents. If the ratio of dads to moms is 3:4, what percent of the people attending the game were moms? (Round your answer to the nearest percent.)

Please show your work if possible!
Thank you :)

3/4 or 75% of the people were students.
thus,
100 - 75 = 25% of the people were parents (moms & dads)
of these, there are 3 dads to 4 moms. Note that the total is 3 + 4 = 7 parents. We can say that 4/7 or 57.14% of the parents are moms. 25% of this is the percent mom:
(25% * 57.14%)/100 = 14.29% = 14%

hope this helps~ :)
