Solution

Find the two numbers.

The ratio of the numbers is 2:5.

If the first integer is 2x, the second integer must be 5x.

The difference between the whole numbers is66.

The equation formed such that difference between the whole numbers is 66 is as follows :

5x-2x=66

Solve the obtained equation:

5x-2x=663x=66x=22

Put x=22 in 2x and 5x to find the integers:

2x=2×222x=44

and

5x=5×225x=110

So, the integers are 44and110.
