FAQs on Decimal Video Lecture - Mathematics Olympiad for Class 3
| 1. What is a decimal number? |  |
Ans. A decimal number is a number that consists of a whole number part and a decimal part separated by a decimal point. It is a way of representing numbers that are not whole or integers.
| 2. How do you read a decimal number? | |
Ans. To read a decimal number, we read the whole number part first, followed by the decimal part. For example, the decimal number 3.75 is read as "three point seven five."
| 3. How do you convert a decimal into a fraction? | |
Ans. To convert a decimal into a fraction, we count the number of decimal places and make the decimal part the numerator of the fraction. The denominator is determined by the number of decimal places. For example, 0.5 can be converted to 1/2, where the numerator is 5 (decimal part) and the denominator is 10 (one decimal place).
| 4. How do you add or subtract decimal numbers? | |
Ans. To add or subtract decimal numbers, we align the decimal points and perform the addition or subtraction operation as usual. The decimal point in the resulting sum or difference should be placed directly below the decimal points in the given numbers.
| 5. Can decimal numbers be negative? | |
Ans. Yes, decimal numbers can be negative. The negative sign (-) is placed before the whole number part of the decimal number. For example, -2.75 represents a negative decimal number.
