Question

1. 4 friends go out for lunch and order a pizza. The first 3 friends take 1/3, 1/4, and 1/6 of
the pizza. Find how much did the fourth friend get?​

Answer 1

Answer:

I guess the answer should be 3/4(I'm not sure)

Answer 2

Answer:

pizza consumed by 3 friends

$\frac{1}{3} + \frac{1}{4} + \frac{1}{6} = \frac{4 + 3 + 2}{12} = \frac{9}{12}$

thus pizza consumed by 4th friend

$1 - \frac{9}{12} = \frac{12 - 9}{12} = \frac{3}{12} = \frac{1}{4}$
