FAQs on Fun Video: How to Compare Numbers ? Video Lecture - Mathematics & Pedagogy - CTET & State TET

1. What are the basic rules of comparing numbers?
Ans. To compare two numbers, we need to see which number is greater than the other. We use the following symbols to compare numbers: ">" means greater than, "<" means less than, and "=" means equal to.
2. How do we compare decimals?
Ans. To compare decimals, we need to compare the digits in each decimal place starting from the leftmost digit. If the leftmost digits are equal, we move to the next decimal place until we find digits that are different.
3. How do we compare fractions?
Ans. To compare fractions, we need to find a common denominator. Once we have a common denominator, we can compare the numerators. If the numerators are equal, then we compare the denominators.
4. Can we compare numbers with different units?
Ans. Yes, we can compare numbers with different units, but we need to convert them to a common unit before we can compare them. For example, we can convert 1 meter to 100 centimeters and compare it to 120 centimeters.
5. How do we compare negative numbers?
Ans. To compare negative numbers, we need to look at the signs. A negative number is always less than a positive number. If we are comparing two negative numbers, then the one with the smaller absolute value is greater. For example, -5 is greater than -10.
