Question

the number of numbers that are divisible by 9 between 1 to 1000 is​

Answer 1

Answer:109

There are 111 numbers between 1 and 1000 divisible by 9.

Step-by-step explanation:

Least number divisible by 9= 9

common difference = 9

Largest number divisible by 9= 999

No of terms =[( last term - first term )÷ common difference]-1

=[ (999-9)÷9]-1

[990÷9]-1= 110-1=109

Answer 2

Here, a=9

a+(n-1)d=999

d=9, a=9

9+(n-1)9=999

9+9n-9=999

9-9+9n=999

0+9n=999

9n=999

n=999/99

n=111
