Write the ratios 5 : 3, 7 : 5 and 6 : 4 in descending order.

Correct option is A

Given :

5 : 3

7 : 5

6 : 4

Solution:

​$$\frac{5}{3} = 1.6667$$​​

​$$\frac{7}{5} = 1.4$$​​

​$$\frac{6}{4} = 1.5$$​​

Now, comparing the values:

1.6667 > 1.5 > 1.4

The ratios in descending order are: 5 : 3, 6 : 4, 7 : 5.

Thus, option (a) is right.
