Question

Eric eats 1/6 of an apple pie and Jack eats 1/4 of the appel pie. How much of the pie has been eaten?

A 1/5
B 5/12
C 7/12
D 1/3

Answer 1

You have to add the fractions, but to do that you have to find the least common denominator

Answer 2

The equation would look like this \[\frac{ 1 }{ 6 } + \frac{ 1 }{ 4 }\]
However, you need to find the LCD before you add.

Answer 3

it would be 5/12 cause the lease common deminator is 12 cause 6*2 and 4*3

Answer 4

The LCD would be 12. So, multiply 1 and 6 by 2, and multiply 4 and 1 by 3.
You'd get:
\[\frac{ 2 }{ 12 } + \frac{ 3 }{ 12 }\]
Now just add the fractions.
2 + 3 = 5
So, the answer is 5/12.
