Mathematics is an essential part of our lives, and we use it almost every day. One of the basic mathematical operations is division, which is used to split a number into equal parts. In this article, we will discuss how to calculate the answer to the simple division problem of 30 divided by 12.
What is Division?
Division is an arithmetic operation that is used to split a number into equal parts. It is the opposite of multiplication. For example, if we have ten candies and we want to split them equally between two people, we will divide 10 by 2, which gives us 5 candies each.
How to Divide 30 by 12?
To divide 30 by 12, we need to follow a simple process:
- Write the dividend (30) and the divisor (12) in a division format.
- Start with the leftmost digit of the dividend (3) and divide it by the divisor (1).
- Write the quotient (2) below the first digit of the dividend.
- Multiply the divisor (12) by the quotient (2) to get the product (24).
- Subtract the product (24) from the first two digits of the dividend (30) to get the remainder (6).
- Bring down the next digit of the dividend (0) next to the remainder (6) to get 60.
- Repeat steps 2 to 5 until there are no more digits left in the dividend.
- The final answer is the quotient (2) with the remainder (6) as a fraction, which is written as 2 6/12 or 2 1/2 in simplified form.
Why is it important to know how to divide?
Division is an essential mathematical operation that we use in our everyday lives. We use it to split bills equally, calculate time, and even in cooking and baking. Without division, it would be difficult to split things equally and accurately.
Other Examples of Division
Here are some other examples of division:
- 10 divided by 5 equals 2
- 25 divided by 5 equals 5
- 36 divided by 9 equals 4
- 100 divided by 10 equals 10
Common Mistakes to Avoid
When dividing numbers, there are some common mistakes that people make. Here are some of them:
- Forgetting to carry over the remainder to the next step.
- Dividing the wrong digit in the dividend.
- Not checking the answer for correctness.
