Question

Write even multiples of 9 less than 100.

Answer 1

Hint: First find multiples of 9 less than 100 and then separate even numbers from it.

Complete step-by-step answer:
First find multiples of 9 less than 100.
So 0 is the first multiple and 99 will be the last multiple definitely. But in between multiples are
18,27,36,45,54,63,72,81,90.
So total 0,9,18,27,36,45,54,63,72,81,90 and 99.
Among them we need only even multiples .
So they are 0,18,36,54,72,90.
Multiples of 9 less than 100 are 0, 18, 36, 54, 72, 90.

Additional information:
Multiples are what we get after multiplying a number by an integer(not a fraction).
The first multiple of every number is that number itself.
Every number is a multiple of one.
0 is multiple of every number (except 0) as the product of 0 with any number is 0.
Multiples are useful in finding the LCM.
Table of a number is its multiples up to 10.
Multiple is just a number , it can be odd, even, prime or composite.
Number of multiples of a given number are infinite.

Note: Every number is a multiple of itself. So you should consider the same number in count of multiple also.
