Question 6 of 42intermediate💡 UnderstandShort Answer2 marks

6×146 \times 14 can be obtained by splitting the arrangement into two equal groups.

6×14=Double of 6×7 Why?6 \times 14 = \text{Double of } 6 \times 7 \text{ Why?}
Correct Answer

Reason: 14 can be split as 7+77 + 7.

Calculation:

6×14=6×7+6×76 \times 14 = 6 \times 7 + 6 \times 7 =42+42= 42 + 42 =84= 84

Conclusion: Since both parts are equal, we can simply double 6×76 \times 7.

Answer: 6×14=Double of 6×7=846 \times 14 = \text{Double of } 6 \times 7 = \mathbf{84}

Explanation

The chapter shows that when a number can be split into two equal parts (like 14=7+714 = 7 + 7), the multiplication can be done by doubling. 6×14=6×7+6×7=2×(6×7)=double of 42=846 \times 14 = 6 \times 7 + 6 \times 7 = 2 \times (6 \times 7) = \text{double of } 42 = 84.

Solution Steps

  1. Split 14 as 7 + 7

  2. Calculate 6×76 \times 7 = 42

  3. Double 42 to get 84
