Mathematics is an essential part of our daily lives, and having a good grasp of basic arithmetic operations is vital for problem-solving and decision-making. In this article, we will delve into the world of division and explore the concept of 100 divided by 25.
Understanding Division
Division is one of the four fundamental arithmetic operations, along with addition, subtraction, and multiplication. It involves sharing a certain quantity into equal parts or groups. In mathematical terms, division is represented by the symbol ÷ or /. For instance, 100 ÷ 25 or 100 / 25.
What is 100 Divided by 25?
To solve this problem, we need to divide 100 by 25. This can be done using long division, mental math, or a calculator.
Using Long Division
Long division is a step-by-step process of dividing a number by another number. To divide 100 by 25 using long division:
- Write the dividend (100) on top of a line, and the divisor (25) below it.
- Divide the first digit of the dividend (1) by the divisor (25). Since 25 does not go into 1, we move to the next digit.
- Divide the first two digits of the dividend (10) by the divisor (25). Since 25 goes into 10 zero times, we write 0 on top of the line.
- Multiply the divisor (25) by the result (0) and subtract the product from the dividend (10).
- Bring down the next digit of the dividend (0) and repeat the process.
- Divide the remaining digits of the dividend (100) by the divisor (25).
Using Mental Math
Mental math is a quick and efficient way to perform arithmetic operations in your head. To divide 100 by 25 using mental math:
- Think of 100 as 4 sets of 25.
- Since 25 x 4 = 100, we can conclude that 100 divided by 25 is equal to 4.
Using a Calculator
A calculator is a handy tool for performing arithmetic operations quickly and accurately. To divide 100 by 25 using a calculator:
- Enter the dividend (100) into the calculator.
- Press the division symbol (÷ or /).
- Enter the divisor (25) into the calculator.
- Press the equals symbol (=).
The result of 100 divided by 25 is 4.
