Question

what is fraction? Define all type of fractions with example and what is mole fraction​

Answer 1

Improper fraction:

Fractions with the numerator either equal to or greater than the denominator are called improper fraction. (Numerator = denominator or, Numerator > denominator)

Fractions like 54, 175, 52 etc. are not proper fractions. These are improper fractions. The fraction 77 is an improper fraction.

The fractions 54, 32, 83, 65, 103, 1310, 154, 99, 2013, 1212, 1311, 1411, 1717 are the examples of improper fractions. The top number (numerator) is greater than the bottom number (denominator). Such type of fraction is called improper fraction.

Notes:

(i) Every natural number can be written as a fraction in which 1 is it's denominator. For example, 2 = 21, 25 = 251, 53 = 531, etc. So every natural number is an improper fraction.

(ii) The value of an improper fraction is always equal to or greater than 1.

Mixed fraction:

A combination of a proper fraction and a whole number is called a mixed fraction.

113, 213, 325, 425, 11110, 91315 and 1235 are examples of mixed fraction.

Two 12, make a whole.

Mixed Numbers

12 12

12 + 12 = 22 = 1

What will you get if you add one more 12 to a whole?

Mixed Fraction

12 + 12 + 12 = 1 + 22 = 112

Now, you have three half or you can say that you have a whole and a half or 12.

Number such as 112 is a mixed number.

A fraction is a number representing a part of a whole.

The whole may be a single object or a group of objects.

Numbers such as half, one-third, three-fifths etc. are fractional numbers.
