Rose is baking cupcakes for her class. She adds of a cup of sugar to the mixing bowl. Then, she realizes she added too much and takes of a cup of sugar out of the bowl. Which of the following equations represents how much sugar she has left in the bowl?(1 point)
1. 3/4 + 1/3 = 13/12
2. 3/4 + (-1/3) = 5/12
3. -3/4 + (-1/3) = -13/12
4.-3/4 + 1/3 = -5/12
2. 3/4 + (-1/3) = 5/12
To find how much sugar Rose has left in the bowl, we need to subtract the amount of sugar she took out from the amount she added in the beginning.
The amount she added is 1/4 of a cup of sugar.
The amount she took out is 1/3 of a cup of sugar.
To find the difference, we can subtract 1/3 from 1/4:
1/4 - 1/3
To subtract fractions, we need a common denominator. In this case, the least common denominator of 4 and 3 is 12.
Converting the fractions to have a denominator of 12:
1/4 = 3/12
1/3 = 4/12
Now we can subtract:
3/12 - 4/12 = -1/12
Therefore, the correct equation representing the amount of sugar she has left in the bowl is:
3/4 + (-1/3) = 5/12
So the answer is option 2.
