 # RD Sharma Solutions Class 6 Mathematics Solutions for Operations on whole numbers Exercise 4.3 in Chapter 4 - Operations on whole numbers

Find each of the following products:

(i) 736 × 93

(ii) 816 × 745

(iii) 2032 × 613

(i) 736 × 93

It can be written as

= 736 × (100 – 7)

By using distributivity of multiplication over subtraction of whole numbers

= (736 × 100) - (736 × 7)

On further calculation

= 73600 – 5152

We get

= 68448

(ii) 816 × 745

It can be written as

= 816 × (750 – 5)

By using distributivity of multiplication over subtraction of whole numbers

= (816 × 750) - (816 × 5)

On further calculation

= 612000 – 4080

We get

= 607920

(iii) 2032 × 613

It can be written as

= 2032 × (600 + 13)

By using distributivity of multiplication over addition of whole numbers

= (2032 × 600) - (2032 × 13)

On further calculation

= 1219200 – 26416

We get

= 1245616
