FAQs on Decimals Video Lecture - Mathematics for Class 4

1. What are decimals and how are they used in everyday life?

Ans.Decimals are numbers that represent a whole number combined with a fractional part, separated by a decimal point. They are used in everyday life for tasks such as measuring length, weight, and volume, as well as in currency to represent cents. For example, $4.50 indicates four dollars and fifty cents.

2. How do you add and subtract decimals?

Ans.To add or subtract decimals, align the numbers by the decimal point and fill in any empty spaces with zeros. Then, perform the addition or subtraction as you would with whole numbers. Finally, place the decimal point in the result directly below the decimal points of the numbers you added or subtracted.

3. What is the difference between a terminating decimal and a repeating decimal?

Ans.A terminating decimal is a decimal that has a finite number of digits after the decimal point, such as 0.75 or 1.5. A repeating decimal, on the other hand, has one or more digits that repeat indefinitely, such as 0.333... (which represents one-third) or 0.666... (which represents two-thirds).

4. How can you convert a fraction to a decimal?

Ans.To convert a fraction to a decimal, divide the numerator (the top number) by the denominator (the bottom number). For example, to convert 1/4 to a decimal, divide 1 by 4, which equals 0.25.

5. Why is it important to learn about decimals in mathematics?

Ans.Learning about decimals is important because they are widely used in various fields, including finance, science, and everyday measurements. Understanding decimals helps students perform calculations accurately, interpret data, and make informed decisions in real-life situations.
