Answer 1

The appropriate and equivalent expression is listed below ;

• (3 × 4) + (3 × 7) = 3(4 + 7)
• (5 × 9) - (5 × 6) = 5(9 - 6)
• (32 + 16) = 48 = 8(4 + 2)
• 4(100 - 3) = 97 × 4
• 7(60+6) = 66 × 7

(3 × 4) + (3 × 7)

Factorize :

Since 3 is common to both sides :

(3 × 4) + (3 × 7) = 3(4 + 7)

(5 × 9) - (5 × 6)

Factorize :

5 common to both sides :

(5 × 9) - (5 × 6) = 5(9 - 6)

(32 + 16) = 48

A common multiple of both 32 and 16 = 8

(8 × 4) = 32

(8 × 2) = 16

Hence,

(8 × 4) + (8 × 2) = 48

(8 × 4) + (8 × 2)

Factorize :

8(4 + 2)

4(100 - 3)

Expand by Open the bracket :

4(97) = 4 × 97

7(60 + 6)

Expand by Open the bracket :

7(66) = 66 × 7
