pete colored 1/2 of a poster. rebecca colored 1/3 of a poster. what fraction still needs to be colored?

1/2 = 3/6

1/3 = 2/6

3/6 + 2/6 = 5/6

6/6 - 5/6 = 1/6

1/1

To find the fraction that still needs to be colored, we need to subtract the fractions that Pete and Rebecca already colored from the whole poster.

Pete colored 1/2 of the poster, and Rebecca colored 1/3 of the poster.

To get a common denominator, we need to find the least common multiple (LCM) of 2 and 3, which is 6.

We can convert 1/2 and 1/3 to the same denominator of 6:

Pete's fraction becomes 3/6 (since 3 multiplied by 2 is 6).
Rebecca's fraction becomes 2/6 (since 2 multiplied by 3 is 6).

Now we can subtract these fractions from 1 (representing the whole poster) to find the fraction that still needs to be colored:

1 - (3/6 + 2/6)
1 - 5/6
(6/6) - (5/6)
1/6

Therefore, the fraction that still needs to be colored is 1/6.

To determine the fraction of the poster that still needs to be colored, we need to subtract the fraction already colored by Pete and Rebecca from the whole poster.

Let's first find the common denominator for 1/2 and 1/3, which is 6.

To make the denominators 6, we can rewrite 1/2 as 3/6 and 1/3 as 2/6.

Now, we can subtract the fractions:

3/6 - 2/6 = 1/6.

So, 1/6 of the poster still needs to be colored.
