Answer:
Step-by-step explanation:
It's simple
Firstly put the digits to which the number is to be multiplied (11). Now, write the number 2 single time less than the number of digit in number to which 11 is multiplied.
For e.g.
11111111 × 11=
Here, firstly write the digits of 11 at starting and end I.e. 1_________1
Now coun the digits in the no. To which 11 is multiplied here it's 8 digits. So one less than 8 is 7.
Thus answer is 122222221.
Hope's it help.
Answer:
11111 × 11 = 122221
111111 × 11 = 1222221
1111111 × 11 = 12222221
Step-by-step explanation:
(a) × (b) = (c)
1. 1 × 11 = 11
2. 11 × 11 = 121
3. 111 × 11 = 1221
4. 1111 × 11 = 12221
In the above series, we can see that in (a), the no. of digits are increasing with 1. So the next numbers will be 11111, 111111, 1111111 and so on... As for (b), the no. is constant, which is 11. So the next numbers will 11, 11, 11 and so on.....And as for (c), the no. '2' in the middle of '11' are increasing as per the no. of '1''s are increasing in (a). So the numbers will be 122221, 1222221, 12222221 and so on.....
Therefore the series will continue like:
5. 11111 × 11 = 122221
6. 111111 × 11 = 1222221
7. 1111111 × 11 = 12222221
8. 11111111 × 11 = 122222221
9. 111111111 × 11 = 1222222221
10. 1111111111 × 11 = 12222222221 and so on........
