Multiples of 90 are the numbers that can be divided by 90 without leaving any remainder. Interestingly, the multiples of 90 can be derived from the multiples of 9 by multiplying them by 10. The first five multiples of 9 are 9, 18, 27, 36, and 45. If we multiply each multiple of 9 by 10, the numbers obtained will be the multiples of 90.

10 × 9 (Multiple of 9) = 90 (Multiple of 90)10 × 18 = 18010 × 27 = 27010 × 36 = 36010 × 45 = 450

Hence, the first five multiples of 90 are 90, 180, 270, 360, and 450.

## Multiples of 90 Solved Examples

Example 1: On a highway, there is a fuel station every 90 miles and a restaurant every 120 miles. After how many miles, would you find a fuel station and a restaurant at the same place?

Solution:

Distance between two fuel stations = 90 kmTherefore, there will be a fuel station at 90 km, 180 km, 270 km, 360 km, 450 km….Distance between two restaurants = 120 kmTherefore, there will be a restaurant at 120 km, 240 km, 360 km, 480 km, 600 km…Thus, from the above, we can say that after 360 km, there will be a fuel station and restaurant at the same place.
