Question

Solve for v in the proportion.

40/48 = v/12
v =

Answer 1

To solve for \( v \) in the proportion \( \frac{40}{48} = \frac{v}{12} \), we can use cross-multiplication.

This means we multiply across the equals sign:

\[
40 \times 12 = 48 \times v
\]

Calculating the left side:

\[
40 \times 12 = 480
\]

So we have:

\[
480 = 48v
\]

Next, we can solve for \( v \) by dividing both sides by 48:

\[
v = \frac{480}{48}
\]

Calculating that gives:

\[
v = 10
\]

Therefore, the value of \( v \) is 10.
