Yes! Both are right!
To find the total amount of butter Tanya needs for her cake and frosting, we need to add the fractions 3/8 and 1/4 together.
To add fractions, we first need to make sure they have a common denominator. In this case, the denominators are 8 and 4. The least common multiple of 8 and 4 is 8.
To convert the fractions to have the same denominator of 8, we multiply the numerator and denominator of 3/8 by 2 (since 4 divided by 2 is 2) and the numerator and denominator of 1/4 by 2 (since 8 divided by 4 is 2).
After converting, we get 6/8 for 3/8 and 2/8 for 1/4.
Now, we can add the fractions together: 6/8 + 2/8 = 8/8.
Therefore, the total amount of butter Tanya needs for her cake and frosting is 8/8, which is equivalent to 1 whole stick of butter.
Since none of the options A, B, C, or J represents 1 whole stick of butter, the correct answer is not provided.
