Question

John ate 1/2 of a pizza for lunch, and he ate 1/3 of what was left for dinner. How much pizza did john eat for dinner?

A) 1/12
B) 1/3
C) 1/6
D) 1/9

Answer 1

1/2 + (1/3)(1-1/2)
= 1/2 + (1/3)(1/2)
= 1/2 + 1/6
= 3/6 + 1/6
= 4/6
= 2/3

Answer 2

does any know?

Answer 3

So, C

Answer 4

Its C! thx

Answer 5

Lets see if its A:

If it were A he would've eaten 6/12 for lunch which would leave 6/12 that means he would've eaten 2/12 for dinner because 1/3 of 6/12 is 2/12 but that's not an option so it's not A

Lets see if its B:

we know it's not B because the problem stated that he ate 1/3 of what was left not the whole to begin with

Lets see if its C:

using the same way we figured out if it was A we need to find what 1/2 is equal to in this case it's 3/6 so we have 3/6 left that means we need to know what 1/3 of 3/6 is, the answer is 1/6 so C is correct

sorry for the long explanation hope it helps 😃
