Question

Check whether the following are in proportion or not 8:5 and 7:9​

Answer 1

Answer:

• The given ratios $8:5$ and $7:9$ are not in proportion.

Step-by-step explanation:

Given : The two ratios are given $8:5$ and $7:9$.

To find : Check whether the given ratios are in proportion or not.

Solution :

• The given ratios are $8:5$ and $7:9$.
• We have to check that these given ratios are in proportion or not.
• To be proportion, the ratios should have equal values.
• To check that, we have to find the values of given ratios.

            ∴ $\frac{8}{5} = 1.6$    (i)

       and $\frac{7}{9}= 0.777$    (ii)

• From (i) and (ii), we get

               $\frac{8}{5} \neq \frac{7}{9}$

• The given ratios $8:5$ and $7:9$ are not in proportion.
