Now let’s look at the operations with whole numbers and Fractions:

All mathematical operations namely addition, subtraction, multiplication and division are possible with whole numbers and the fractions.

We first take addition of a Whole Number with a fraction

Say

Add 4 and 3/5

Now 4 can be written as 4/1 so

4/1 + 3/5

LCM of 1 and5 is 5

So it becomes

20/5 + 3/5 (by multiplying & dividing 4 / 1 by 5 )

= ( 20 + 3 ) / 5

= 23 / 5.

Similarly subtraction of a whole number and a fraction can also be performed

Solve: 3 - ( 3/5 )

Now 3 can be written as 3/1 so

3/1 - 3/5

l cm of 1 and 5 is 5

so it becomes

15/5 - 3/5 (by multiplying & dividing 4 / 1 by 5 )

= ( 15- 3 ) / 5

= 12 / 5.

To multiply, we proceed as:

(7 / 6) * 8

It can be written as

(7 / 6) * (8/1)

Here we multiply numerator with the numerator and the denominator with the denominator, we get

= (7 * 8) /(6 * 1)

= 56 / 6

To divide we convert the divisor into its reciprocal and change the sum into simple sum of multiplication.

Thus all mathematical operators can be performed on a whole number and a fraction.
