Question

Find all the multiples of 9 up to 100.

Answer 1

Hint: Use the multiplication table of 9 to find the values up till 100.
Multiply 9 with the natural numbers 1, 2, 3, 4 …… until a value below 100 is received.

Complete step-by-step answer:
We can find the multiple of 9 if we know the multiplication table of 9.
The multiplication table is a mathematical table used to define a multiplication operation for an algebraic system. Here we need to find the multiples of 9 up to 100.
9 multiplied by 1 gives, $$9\times 1=9$$.
9 multiplied by 2 gives, $$9\times 2=18$$.
9 multiplied by 3 gives, $$9\times 3=27$$.
9 multiplied by 4 gives, $$9\times 4=36$$.
9 multiplied by 5 gives, $$9\times 5=45$$.
9 multiplied by 6 gives, $$9\times 6=54$$.
9 multiplied by 7 gives, $$9\times 7=63$$.
9 multiplied by 8 gives, $$9\times 8=72$$.
9 multiplied by 9 gives, $$9\times 9=81$$.
9 multiplied by 10 gives, $$9\times 10=90$$.
9 multiplied by 11 gives, $$9\times 11=99$$.
9 multiplied by 12 gives, $$9\times 12=108$$.
Now we can see that $$9\times 12$$ gives 108 which is greater than 100.
So the required multiples of 9 up to 100 are : 9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99. Hence we got all the required multiples.

Note: You can also draw a table to find the multiple of 9.

X	0	1	2	3	4	5	6	7	8	9	10	11	12
9	0	9	18	27	36	45	54	63	72	81	90	99	108

Similarly, you can find the multiple of any natural number.
