\( a = 10 \)

Solución

To solve the equation 16/20 = 8/a, we can cross-multiply:   16 × a = 20 × 8 This gives:   16a = 160 Now, divide both sides by 16:   a = 160 ÷ 16 Thus:   a = 10

Beyond the Answer

To solve the equation \( \frac{16}{20}=\frac{8}{a} \), we can cross-multiply. This gives us \( 16a = 8 \times 20 \). Simplifying the right side, we find \( 16a = 160 \). To isolate \( a \), divide both sides by 16, resulting in \( a = 10 \). To double-check your work, plug \( a \) back into the original equation: \( \frac{8}{10} = \frac{4}{5} \), which is equivalent to \( \frac{16}{20} \). It fits! So, the solution is \( a = 10 \).
