Question

A learner did a long division sum 2646*13 And found the answer 23 remainder by 7 give a concept and the reason

Answer 1

We can use multiplication to check your division answer this way.

Multiply the quotient times the divisor.

$$23\cdot13=299$$

Since there is a remainder, add it to the multiplication product.

$$299+7=306$$

Compare this answer to the dividend. They should be the same number.

Since $306\not=2646,$ we conclude that a leraner is wrong.
