300*(1-3/4) = 300 * 1/4 = ?

(1-1/3)? = 2/3? = ??

Find ? then ??

Answer 2

Is it 50??

Answer 3

Because 300 * 1/4 = 75

And I did 2/3 * 75 = 50

So it has to be 50

Answer 4

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.
