Question

$12\times 6$ is equal to _______.

• A. $(6\times 10)+(4\times 3)$
• B. $(10\times 2)+(8\times 4)$
• C. $(35\times 2)+(2\times 1)$
• D. $(5\times 6)+(21\times 2)$

Answer 1

Answer: (A), (C), (D)

The correct options are
A $(6\times 10)+(4\times 3)$
C $(35\times 2)+(2\times 1)$
D $(5\times 6)+(21\times 2)$

$12\underset{–}{\times 6}72$

We see that

• $A.(6\times 10)+(4\times 3)\Rightarrow 60+12=72$

• $B.(10\times 2)+(8\times 4)\Rightarrow 20+32=52$

• $C.(35\times 2)+(2\times 1)\Rightarrow 70+2=72$

• $D.(5\times 6)+(21\times 2)\Rightarrow 30+42=72$

So, we see that a number can be represented in many ways.
