Chapter CSB, Problem 1.8E

To determine

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

Answer to Problem 1.8E

No.

Explanation of Solution

Given:

The given pairs of ratios are $\frac{16}{17},\frac{8}{9}$ .

Calculation:

As the given pairs of ratios are $\frac{16}{17},\frac{8}{9}$ .

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

  $\begin{array}{l}\frac{16}{17}=\frac{2\times 2\times 2\times 2}{17}\left\{\text{factor}\right\}\\ \frac{8}{9}=\frac{2\times 2\times 2}{3\times 3}\{\text{factor}}\end{array}$

Thus, the factor of each proportion is notsame.

No, the given pairs of ratios form a proportion.
