Chapter 7: Q7. (page 344)

Solve the proportion.
$\frac{30}{48} = \frac{10}{h}$

Short Answer

Expert verified

The value of $h$ in the given proportion is 16.

Step by step solution

Step 1. Given Information.

The proportion is $\frac{30}{48} = \frac{10}{h}$ .

Step 2. Formula used.

Cross-product property:

If $\frac{a}{b} = \frac{c}{d}$ , where $b \neq 0$ and $d \neq 0$ , then $a d = b c$ .

Step 3. Calculation.

Consider the proportion given:

$\frac{30}{48} = \frac{10}{h}$

Use cross product property.

$\begin{matrix} 30 \cdot h = 48 \cdot 10 \\ 30 h = 480 [multiply] \\ \frac{30 h}{30} = \frac{480}{30} [divideeachsideby30] \\ h = 16 [simplify] \end{matrix}$

Hence,

$\frac{30}{48} = \frac{10}{16}$

Step 4. Conclusion.

The value of $h$ in the given proportion is 16.
