FAQs on Mindmap: Fractions and Decimals - Mathematics (Maths) Class 7

1. What are the basic differences between fractions and decimals?
Ans. Fractions represent a part of a whole and are written as two numbers separated by a slash (e.g., 1/2), while decimals are a way of expressing fractions in a base-10 system, using a decimal point (e.g., 0.5). Both represent the same value, but the format is different.
2. How can I 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 3/4 to a decimal, divide 3 by 4, which equals 0.75.
3. How do I add fractions and decimals together?
Ans. To add fractions and decimals, first convert the fraction to a decimal or vice versa. For example, to add 1/2 and 0.75, convert 1/2 to 0.5, then add 0.5 + 0.75 = 1.25.
4. What are some common fractions and their decimal equivalents?
Ans. Some common fractions and their decimal equivalents include: 1/2 = 0.5, 1/4 = 0.25, 3/4 = 0.75, and 1/8 = 0.125. These conversions are useful for quick calculations.
5. How do I simplify a fraction?
Ans. To simplify a fraction, divide both the numerator and the denominator by their greatest common divisor (GCD). For example, to simplify 8/12, find the GCD, which is 4. Divide both 8 and 12 by 4 to get 2/3.
