Question

Sean painted 1/3 of a fence. Sandra painted 1/4 of the fence. How much

of the fence remains to be painted?

Answer 1

Answer:7/12

Step-by-step explanation:

1/3 = 4/12

1/4=3/12

3/12+4/12 = 7/12

7/12 is the answer

Answer 2

Sean and Sandra painted a combined total of 7/12 of the fence, so 5/12 of the fence remains unpainted.

Step-by-step explanation:

The question is asking us to calculate the remaining portion of a fence that has not been painted after Sean and Sandra have painted their parts. Sean has painted 1/3 of the fence, and Sandra painted 1/4 of the fence. To determine the unpainted portion, we need to add the fractions representing the painted parts and subtract that sum from the whole.

First, let's find a common denominator which is 12 in this case. Sean's portion becomes 4/12 and Sandra's portion becomes 3/12. Adding Sean's and Sandra's portions gives us 7/12.

Now, subtract the painted portion from the whole, which represents 1 or 12/12.
1 (12/12) - 7/12 = 5/12

Thus, 5/12 of the fence remains to be painted.
