Chapter CSB, Problem 1.3E

To determine

To check:whether thegiven pairs of ratios forms a proportion.

Answer to Problem 1.3E

No.

Explanation of Solution

Given:

The given pairs of ratios are $\frac{2.3}{3.4},\frac{3.0}{3.6}$ .

Calculation:

As the given pairs of ratios are $\frac{2.3}{3.4},\frac{3.0}{3.6}$ .

Now, to find the factor of the ratio so that to check that each proportion is same or not. Therefore,

  $\begin{array}{l}\frac{2.3}{3.4}=\frac{23\times 0.1}{17\times 2\times 0.1}=\frac{23}{34}\left\{\text{factor}\right\}\\ \frac{3.0}{3.6}=\frac{2\times 3\times 5\times 0.1}{2\times 2\times 3\times 3\times 0.1}=\frac{5}{6}\{\text{factor}}\end{array}$

Thus, the factor of each proportion is not same.

No, the given pairs of ratios form a proportion.
