FAQs on Decimals Video Lecture - Mathematics (Maths) Class 6

1. What is a decimal number?
Ans. A decimal number is a number that includes a decimal point to represent a fraction or a part of a whole. It is a number system that uses the base-10 system, where each digit can have a value from 0 to 9.
2. How do you read a decimal number?
Ans. To read a decimal number, start by reading the whole number part before the decimal point. Then, say "and" before reading the digits after the decimal point individually. For example, the decimal number 3.141 would be read as "three and one hundred forty-one thousandths."
3. How do you add decimal numbers?
Ans. To add decimal numbers, align the decimal points of the numbers being added. Then, add the digits to the right of the decimal point, just like adding whole numbers. Finally, place the decimal point in the sum directly below the aligned decimal points of the given numbers.
4. How do you multiply decimal numbers?
Ans. To multiply decimal numbers, first, ignore the decimal point and multiply the numbers as if they were whole numbers. Count the total number of decimal places in the original numbers and place the decimal point in the product to make sure it has the correct number of decimal places.
5. How do you convert a decimal number to a fraction?
Ans. To convert a decimal number to a fraction, count the number of decimal places and write the decimal number as the numerator. The denominator should be a power of 10 based on the number of decimal places. Simplify the fraction if possible. For example, 0.75 can be written as 75/100, which simplifies to 3/4.
