Chapter 7: Q8. (page 246)

Complete the statement.
If $\frac{n}{p} = \frac{q}{r} = \frac{7}{9}$ , then $\frac{n + q + 7}{p + r + 9} = \frac{?}{?}$

Short Answer

Expert verified

The final answer is,

$\frac{n + q + 7}{p + r + 9} = \frac{7}{9}$

Step by step solution

Step 1. Given information.

The given proportion is,

$\frac{n}{p} = \frac{q}{r} = \frac{7}{9}$

Step 2. We know the concept as mention below.

if. $\frac{a}{b} = \frac{c}{d} = \frac{e}{f} = ... t h e n \frac{a + c + e + ...}{b + d + f + ...} = \frac{a}{b} = ...$

Step 3. So, by this concept.

we must have,

$\frac{n + q + 7}{p + r + 9} = \frac{7}{9}$

Therefore, the final answer is $\frac{n + q + 7}{p + r + 9} = \frac{7}{9}$ ,
