Reciprocal and division of fractions room two different methods. When the numerator and denominator the a portion are interchanged, then it is stated to it is in it’s reciprocal. Suppose a fraction is a/b, climate it’s reciprocal will certainly be b/a. A fraction is a numerical quantity that is no a totality number. Rather it represents a part of the whole. For example, it tells how numerous slices the a pizza are continuing to be or eating of the totality pizza, such as one-half (½), three-quarters (¾) etc. Department of fractions is an procedure performed ~ above fractions v multiple steps. Also, learn separating fractions here.

Parts that FractionThe portion has two parts:

NumeratorDenominator.

Types that Fraction: Fractions room basically of three types, proper, improper and also mixed. Learn the meanings below.

Proper Fraction: If both the numerator and also denominator space positive, and also the numerator is much less than the denominator, climate it is a ideal fraction.

Example: 2/5, 1/3, 3/6, 7/8. 9/11, etc.

Improper Fractions: Fractions having numerator higher than the denominator are called Improper fractions.

Example: 8/3, 3/2, 6/3, 11/9, etc

Mixed Fraction: When a entirety number and a proper fraction are combined, the is known as a mixed fraction.

All this details to be the basics the fractions. Currently let us learn reciprocal of fractions in addition to its division.

Reciprocal of Fractions

The fraction obtained through swapping or interchanging Numerator and also Denominator through each other is well-known as mutual of the given fraction.

For example, a mutual of 5 is 1/5, a mutual of 8/3 is 3/8.

The mutual of a mixed portion can be obtained by convert it right into an improper fraction and climate swap the numerator and also denominator.

For example, to discover the reciprocal of \(\small 2\frac13\);

Convert the mixed fraction into wrong fraction:\(\small 2\frac13=\frac73\)Now invert the fraction: 7/3 and 3/7, wherein 3/7 is called reciprocal of 7/3 or \(\small 2\frac13\).

Note: The product that a portion and it’s reciprocal is always 1.

Division of Fractions

Division including a fraction follows particular rules. To carry out any department involving fraction just multiply the an initial number through the reciprocal of the 2nd number. Actions are as follows:

Step 1: very first change the division sign (÷) come multiplication authorize (×)

Step 2: If we readjust the sign of department to multiplication, at the same time we have to write the reciprocal of the second term or fraction.

Step 3: Now, main point the numbers and simplify the result.

These rules are typical for:

Division of the totality number by a fraction.Division that a fraction by a totality numberDivision the a portion by one more fraction.

Note: it is to be provided that department of fractions is basically the multiplication of fraction obtained by mutual of the denominator (i.e. Divisor).

Examples of departments of Fractions

Examples because that each the the condition as mentioned previously are described below.

Division that the whole Number by a Fraction

Example 1: 16 ÷ 4/3

Solution: 16 ÷ 4/3 = 16/1 × 3/4

3/4 is the reciprocal of 4/3.

Hence, (16 × 3)/(1×4)

4 × 3 = 12

Therefore,

16 ÷ 4/3 = 12

Division the a fraction by a totality Number

Example 2: Divide 8/3 by 3

Solution: We need to simplify, 8/3 ÷ 3

The reciprocal of 3 is 1/3.

Now composing the provided expression right into multiplication form,

8/3 × 1/3 = 8 /9

Therefore,

8/3 ÷ 3 = 8/9

Division the a fraction by one more Fraction

Example 3: 8/3 ÷ 4/3

Solution: 8/3 ÷ 4/3

Reciprocal of second term 4/3 is 3/4.

Now main point the an initial term with the reciprocal of the second term.

8/3 × 3/4 = 8/4 = 2

Hence,

8/3 ÷ 4/3 = 2

To perform department involving combined fraction, transform the mixed portion into an improper portion and follow the over steps.

The mutual of a portion will attain by interchanging the numerator and also denominator. For example, y/x is the mutual of the fraction x/y, i.e. Y/x = 1/(x/y).
When dividing fractions by entirety numbers, us should transform the department into multiplication by creating the mutual of the divisor, i.e. A entirety number. For example, dividing 2/3 by 2 can be carry out by converting together (2/3) × (1/2). Hence, the leveling becomes simple now.
To simplify the department process when separating fractions, reciprocals are provided so that department will be convert to multiplication. For example, (4/5) ÷ (8/7) have the right to be written as (4/5) × (7/8).

The reciprocal rule of department method is “Multiply the dividend through the reciprocal of the divisor”. In basic words, invert the divisor and multiply through the dividend.
