Division test

How to know if the division we have made is correct

To know if the division we have solved is correct, we will use the following formula:

\text{Dividend} \ = \ \left( \text{divisor} \ \times \ \text{quotient} \right) \ + \ \text{remainder}

If you don’t know or don’t remember what the parts of the division are, click here.

Example of the division test

We will use the following example:

Figure 1

Which leads us to apply the formula mentioned at the beginning of the post:

\ \left( 2 \times 12 \right) \ + \ 1

All the previous operation has to be equal to the dividend (it is the number that is inside the dividing box), carrying out the previous operations we have to:

\ \left( 2 \times 12 \right) \ + \ 1 = 25

As the operation gave us equal to the dividend, then our division is well carried out. Done! With that you check if you made the division correct.

Thank you for being in this moment with us : )
