The topic of GMAT remainders is not a difficult one and probably terminology that you learned back in second or third grade. You likely learned how to find a remainder through long division, and since we have banned you from long division, we are going to have to learn about remainders just a touch differently. Let’s start by looking at a few things related to remainders so that we have a basis to talk about this topic.

*Obviously, you would never write a mixed fraction with a zero in the numerator of the fraction portion, but writing helps convey a point.

As you can see, all of the multiples of 4 {4, 8 and 12} have no remainder and the other numbers have a remainder equal to the difference between itself and the next lower multiple of 4. Thus,

Dividend = Quotient x Divisor + Remainder

You do not need to memorize this formula, although understanding exactly how it works will aide in some GMAT problems.

**Key Points:**

- The quotient is equal to the whole number in the mixed fraction
- The remainder is equal to the numerator of the mixed fraction
- The remainder pattern cycles between zero and 3, which is 1 number less than the divisor
- The fraction part of the mixed fraction is equal to the value to the right of the decimal
