What is a Fraction?
A fraction is a number that represents part of a
whole. The whole can be a single object (like a
cake) or a group of objects (like a set of marbles).
Parts of a Fraction:
Numerator: The top number, which indicates
how many parts are taken.
Denominator: The bottom number, which
indicates the total number of equal parts in the
whole.

Example:
Consider a figure that is divided into 4
equal parts. If 3 parts are shaded, then the
fraction representing the shaded portion is
3/4.
Numerator: 3 (number of shaded
parts)
Denominator: 4 (total number of
parts)

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

1. What is the relationship between fractions and decimals?
Ans. Fractions and decimals are two different ways to represent parts of a whole. Fractions represent parts of a whole as a ratio of two numbers (numerator and denominator), while decimals represent the same parts of a whole using a decimal point and place value system.
2. How can fractions be converted into decimals?
Ans. To convert a fraction into a decimal, divide the numerator by the denominator. The result will be the decimal equivalent of the fraction. For example, 1/2 is equal to 0.5 when converted to a decimal.
3. What is the significance of understanding fractions and decimals in real-life applications?
Ans. Understanding fractions and decimals is crucial in real-life applications such as cooking, budgeting, and measurements. Being able to work with fractions and decimals helps in accurately following recipes, managing finances, and making precise measurements.
4. Can decimals always be converted into fractions?
Ans. Decimals can be converted into fractions by writing the decimal as a fraction with a power of 10 as the denominator. However, not all decimals can be expressed as exact fractions, such as recurring decimals like 0.333... which is equivalent to 1/3.
5. How are fractions and decimals used in mathematical operations?
Ans. Fractions and decimals are used in mathematical operations such as addition, subtraction, multiplication, and division. It is important to be able to convert between fractions and decimals to perform these operations accurately.
