Question

find the unknown number in the proportion
2/3=x/122
round your answer to the nearest hundredth

Answer 1

To solve the proportion \( \frac{2}{3} = \frac{x}{122} \), you can use cross-multiplication.

Cross-multiplying gives:

\[
2 \cdot 122 = 3 \cdot x
\]

Calculating \( 2 \cdot 122 \):

\[
244 = 3x
\]

Next, divide both sides by 3 to solve for \( x \):

\[
x = \frac{244}{3}
\]

Calculating \( \frac{244}{3} \):

\[
x \approx 81.3333
\]

Now, rounding to the nearest hundredth:

\[
x \approx 81.33
\]

So, the unknown number \( x \) is approximately **81.33**.
