Is it 50??
Because 300 * 1/4 = 75
And I did 2/3 * 75 = 50
So it has to be 50
And I did 2/3 * 75 = 50
So it has to be 50
3/4 of 300 = 225 cookies sold. How many cookies did she have remaining? (300-225 = 75) . 75 cookies left. Now she gave the neighbor 1/3 of the cookies left. So how many cookies did she give away? (25 cookies) 1/3 of 75. Ending question: How many cookies did she have left? 50 cookies.
75 - 25 = 50.
75 - 25 = 50.
