Mom left 9 cookies on the plate. Claire came in and took 1/5 of the cookies and 1/5 of a cookie. That’s 14/5 + 1/5 = 2 cookies, leaving 7 cookies. Jane came in and took 1/4 of the cookies and 1/4 of a cookie. That’s 13/4 + 1/4 = 2 cookies, leaving 5 cookies. Noah came and took 1/3 of the cookies and 1/3 of a cookie. That’s 12/3 + 1/3 = 2 cookies, leaving 3 cookies. Nelly came and took 1/2 of the cookies and 1/2 of a cookie. That’s 11/2 + 1/2 = 2 cookies, leaving 1 cookie for Dad.
