Question

The addition problem 15 + 24 can also be expressed as which of the following?

A.
5(3 + 24)


B.
3(5 + 8)


C.
8(3 + 5)


D.
5(3 + 8)

Answer 1

To find an expression that is equivalent to \( 15 + 24 \), we can first calculate the sum:

\[
15 + 24 = 39
\]

Now, we will evaluate each option to see which one also simplifies to 39.

A. \( 5(3 + 24) = 5 \times 27 = 135 \)

B. \( 3(5 + 8) = 3 \times 13 = 39 \)

C. \( 8(3 + 5) = 8 \times 8 = 64 \)

D. \( 5(3 + 8) = 5 \times 11 = 55 \)

Now we can see that option B gives us the same value as \( 15 + 24 \):

\[
\text{Option B: } 3(5 + 8) = 39
\]

Thus, the correct answer is:

\[
\boxed{B}
\]
