Division of Decimal Numbers - 2 Video Lecture - Class 7

Ans. To divide decimal numbers, you need to follow these steps: 1. Set up the division problem as you would with whole numbers. 2. If the divisor (the number you are dividing by) is not a whole number, move the decimal point to the right until it becomes a whole number. 3. Move the decimal point in the dividend (the number being divided) the same number of places to the right. 4. Divide as you would with whole numbers. 5. Place the decimal point in the quotient (the answer) directly above the decimal point in the dividend. 6. If there are any remaining decimal places, add zeros to the right of the quotient.

Ans. Place value in decimal numbers refers to the value assigned to each digit based on its position in the number. In a decimal number, the digits to the left of the decimal point represent whole numbers, while the digits to the right of the decimal point represent parts of a whole. For example, in the number 123.45, the digit 1 is in the hundreds place, the digit 2 is in the tens place, and the digit 3 is in the ones place. The decimal point separates the whole number part from the decimal part. The digit 4 is in the tenths place, and the digit 5 is in the hundredths place. Understanding place value is essential for performing operations like addition, subtraction, multiplication, and division with decimal numbers.

Ans. When dividing a decimal number by a whole number, follow these steps: 1. Set up the division problem as you would with whole numbers. 2. Ignore the decimal point in the dividend initially and perform the division as if it were a whole number. 3. Once you have the quotient, place the decimal point in the quotient directly above the decimal point in the dividend. 4. If there are any remaining decimal places in the dividend, bring them down and continue dividing as necessary. 5. If the decimal places continue indefinitely, you may need to round the quotient to a desired decimal place.

Ans. When dividing a decimal number by a divisor with decimal places, you need to adjust the decimal point in both the dividend and the divisor. Follow these steps: 1. Move the decimal point in the divisor to the right until it becomes a whole number. 2. Move the decimal point in the dividend the same number of places to the right. 3. Divide the adjusted dividend by the adjusted divisor as you would with whole numbers. 4. Place the decimal point in the quotient directly above the decimal point in the adjusted dividend. 5. If necessary, round the quotient to the desired decimal place.

Ans. When dividing decimal numbers, remainders may occur. If you encounter a remainder, you have a couple of options: 1. You can express the remainder as a fraction or a decimal by extending the division and adding zeros after the decimal point in the dividend. 2. Alternatively, you can round the quotient to a certain decimal place, which eliminates the remainder. This is often done when the division result needs to be expressed in a specific format or precision.
