Chapter 7: Q4. (page 246)

Complete the statement.
If $\frac{c}{d} = \frac{4}{7},$ then $\frac{d}{c} = \frac{?}{?}$ ,

Short Answer

Expert verified

The final answer is $\frac{d}{c} = \frac{7}{4}$ ,

Step by step solution

01

Step 1. Given information.

The given proportion is,

$\frac{c}{d} = \frac{4}{7}$

02

Step 2, Use cross multiplication.

It is given that $\frac{c}{d} = \frac{4}{7}$ ,

So, $7 c = 4 d$

03

Step 3. Now, divide both sides by 4c.

$\begin{array}{l} \frac{7 c}{4 c} = \frac{4 d}{4 c} \\ \frac{7}{4} = \frac{d}{c} \end{array}$

Therefore, the final answer is $\frac{d}{c} = \frac{7}{4}$ ,
