Question

if you're at a party in 1/4 of the people left later 2/3 of the guests left even later 3/4 of those guest left if 9 people were left how many were at the original party ​

Answer 1

Explanation:

Suppose x people at party,

1.

If 1/4th of x left, then 3/4th of x remains. (1 - 1/4 = 4/4 - 1/4 = 3/4)

2.

Now, 2/3rd of 3x/4 left, so 1/3rd of 3x/4 remains (1 - 2/3 = 3/3 - 2/3 = 1/3)

(1/3)×(3x/4) = x/4

3.

3/4th of x/4 left, so 1/4th of x/4 remain (1 - 3/4 = 4/4 - 3/4 = 1/4)

(1/4)×(x/4) = x/16 = 9

x = 16×9 = 144

Answer 2

Explanation:

because

9x4=36

36x3=108

108/3=34
