How Do You Work Out 21 Divided By 3? [Solved]
Wow, that’s easy! 21 divided by 3 is a piece of cake - 7, no remainder.
Division: Division is a mathematical operation that involves dividing one number (the dividend) by another (the divisor).
Quotient: The result of division is called the quotient, which is the number of times the divisor goes into the dividend.
Remainder: If there is a remainder after division, it will be less than the divisor and can be expressed as a fraction or decimal.
Dividing by 21: When dividing by 21, it’s important to remember that any number divided by 21 will have a remainder of 0 if it’s evenly divisible; otherwise, there will be a remainder left over when you divide.
Multiples of 21: Any multiple of 21 can easily be divided by 21 with no remainder; for example, 42 divided by 21 equals 2 with no remainder left over.
Prime Numbers: Prime numbers are numbers that are only divisible by themselves and 1; when dividing prime numbers such as 17 or 19 by 21, there will always be a remainder left over since they cannot be evenly divided into whole numbers without leaving something behind (in this case, 4 and 2 respectively).
21 divided by what? That’s the question! If you divide 21 by 2, you get 10 and a half. Divide it by 3 and you get 7 - not bad! Divide it by 4 and you get 5 - wow! Divide it by 5 and you get 4 - not too shabby. But if you divide 21 by 6, that’s when things start to get tricky. You’ll end up with 3 and a third.
