If $\frac{a}{4} = \frac{b}{7},$ then $\frac{a}{b} = \frac{?}{?}$

Short Answer

Expert verified

The final answer is, $\frac{a}{4} = \frac{b}{7} \Rightarrow \frac{a}{b} = \frac{4}{7}$ .

Step by step solution

Step 1. Given information.

The given proportion is,

$\frac{a}{4} = \frac{b}{7}$ .

It is given that, $\frac{a}{4} = \frac{b}{7}$

Step 2. Use cross-multiplication method.

We get,

$7 a = 4 b$

Step 3. Now, divide both sides by 7b.

$\begin{array}{l} \frac{7 a}{7 b} = \frac{4 b}{7 b} \\ \frac{a}{b} = \frac{4}{7} \end{array}$

So, we get,

$\frac{a}{4} = \frac{b}{7} \Rightarrow \frac{a}{b} = \frac{4}{7}$

Therefore, the final answer is, $\frac{a}{4} = \frac{b}{7} \Rightarrow \frac{a}{b} = \frac{4}{7}$ .
