FAQs on Decimals Video Lecture - Mathematics for Class 3

1. What are decimals?
Ans. Decimals are numerical representations used to express numbers that fall between whole numbers. They are a way of representing fractions in a more convenient and concise form.
2. How do decimals differ from whole numbers?
Ans. Decimals differ from whole numbers in that they include a decimal point, which indicates the position of the fractional part. Whole numbers do not have a fractional part and are represented without a decimal point.
3. How are decimals converted into fractions?
Ans. To convert a decimal into a fraction, we can count the number of decimal places and express the decimal as a fraction with the decimal numerator and a denominator of 10 raised to the power of the number of decimal places.
4. How can decimals be compared and ordered?
Ans. Decimals can be compared and ordered by examining the place value of each digit. Start from the leftmost digit and compare it with the corresponding digit in another decimal. If they are equal, move to the next digit. If they differ, the decimal with the larger digit is considered greater.
5. How are decimals added and subtracted?
Ans. To add or subtract decimals, line up the decimal points, and perform the addition or subtraction as you would with whole numbers. The decimal point in the result should be aligned with the decimal point in the original numbers.
