Answer 2

6.17 × 3.9  = 24.063

6.17 × 3.9

= (617/100) × (39/10)

= (617 × 39) / 1000

Solve 617 × 39

= (600 + 17)  × ( 40 - 1)

= 600 × 40 - 600 × 1 + 17 × 40 - 17 × 1

= 24000 - 600 +  680 - 17

= 24000 + 80 - 17

= 24000 + 63

= 24063

6.17 × 3.9  = 24063/1000

6.17 × 3.9  = 24.063

Hence 6.17 × 3.9  = 24.063
