Perform The Division: $\[ 0.4 \div 132 \\]
Introduction
Division is a fundamental operation in mathematics that involves finding the quotient of two numbers. When it comes to dividing decimal numbers, it's essential to understand the rules and procedures to obtain accurate results. In this article, we will explore the process of performing division with decimal numbers, focusing on the division of 0.4 by 132.
Understanding Decimal Division
Decimal division involves dividing a decimal number by another decimal number. The process is similar to dividing whole numbers, but with an additional step to handle the decimal point. When dividing decimal numbers, it's crucial to remember that the decimal point in the dividend (the number being divided) must be aligned with the decimal point in the divisor (the number by which we are dividing).
Performing the Division
To perform the division of 0.4 by 132, we can follow these steps:
- Write the problem: Write the division problem with the decimal number 0.4 as the dividend and 132 as the divisor.
- Align the decimal points: Align the decimal points in the dividend and divisor.
- Perform the division: Perform the division by multiplying the divisor by a power of 10 to eliminate the decimal point in the divisor.
- Calculate the quotient: Calculate the quotient by dividing the dividend by the product of the divisor and the power of 10.
Step-by-Step Solution
Let's perform the division of 0.4 by 132 step by step:
- Write the problem: 0.4 ÷ 132
- Align the decimal points: 0.4 ÷ 132.0
- Perform the division: Multiply the divisor (132) by a power of 10 to eliminate the decimal point. In this case, we can multiply by 10^2 (100) to get 13200.
- Calculate the quotient: Divide the dividend (0.4) by the product of the divisor (13200) to get the quotient.
Calculating the Quotient
To calculate the quotient, we can use long division or a calculator. Let's use long division to find the quotient:
0.4 ÷ 132.0
To perform long division, we can follow these steps:
- Divide the first digit: Divide the first digit of the dividend (0.4) by the first digit of the divisor (132). In this case, we can divide 0 by 1 to get 0.
- Multiply and subtract: Multiply the result (0) by the divisor (132) and subtract the product from the dividend (0.4). In this case, we can multiply 0 by 132 to get 0, and subtract 0 from 0.4 to get 0.4.
- Bring down the next digit: Bring down the next digit of the dividend (0). In this case, we can bring down 0 to get 0.40.
- Repeat the process: Repeat the process of dividing, multiplying, and subtracting until we have used all the digits of the dividend.
