To solve for the unknown value in the proportion, we need to maintain the equality of the ratios. Given:
\[ \frac{7}{10} = \frac{14}{?} \]
We can solve for the unknown value by cross-multiplying:
\[ 7 \times ? = 10 \times 14 \]
\[ 7? = 140 \]
Now, divide both sides by 7 to solve for ?:
\[ ? = \frac{140}{7} \]
\[ ? = 20 \]
So, the complete proportion is:
\[ \frac{7}{10} = \frac{14}{20} \]
Therefore, \( ? = 20 \).
Example: 2/4 = 8/? = 8/16
7/10 = 14/?
