Question

find the sum of three digit positive multiple of 7 with solution​

Answer 1

Step-by-step explanation:

The process which has been done in the above shortcut has been explained clearly in the following steps.

Step 1 :

To get the first 3 digit number divisible by 7, we have to take the very first 3 digit number 100 and divide it by 7. 

Step 2 :

When we divide 100 by 7 using long division as given above, we get the remainder 2. 

Step 3 :

Now, the remainder 2 has to be subtracted from the divisor 7.

When we subtract the remainder 2 from the divisor 7, we get the result 5 (That is 7 - 2 = 5).

Step 4 :

Now, the result 5 in step 3 to be added to the dividend 100. 

When we add 5 to 100, we get 105.

Now, the process is over. 

So, 105 is the first 3 digit number exactly divisible by 7.

This is how we have to find the first 3 digit number exactly divisib

Answer 2
