Answer 2

Question Analysis

The question asks how much of the painting is left for the girl to draw after she has completed 1/3 of it on the first day and 1/4 of it on the second day.

Answer

To find out how much of the painting is left for the girl to draw, we need to subtract the portions she has already drawn from the total painting.

Let's assume the total painting is represented by the fraction 1.

On the first day, the girl drew 1/3 of the painting. So, the portion left to draw after the first day is 1 - 1/3.

On the second day, the girl drew 1/4 of the remaining portion. So, the portion left to draw after the second day is (1 - 1/3) - (1/4).

To simplify the calculation, let's find a common denominator for 3 and 4, which is 12.

1 - 1/3 = 12/12 - 4/12 = 8/12

(8/12) - (1/4) = 8/12 - 3/12 = 5/12

Therefore, the girl has 5/12 of the painting left to draw.

Explanation

The girl has completed 1/3 of the painting on the first day. This means that she has drawn 1 part out of 3 parts of the painting. So, the portion left to draw after the first day is 1 - 1/3 = 2/3.

On the second day, the girl drew 1/4 of the remaining portion. This means that she has drawn 1 part out of 4 parts of the remaining portion. So, the portion left to draw after the second day is (2/3) - (1/4) = 8/12 - 3/12 = 5/12.

Therefore, the girl has 5/12 of the painting left to draw.
