Question

Explain how multiplying with 6 is alike multiplying with 3

Answer 1

Because 3x2=6 and 2/3 equals 1/6

Answer 2

3 times 2=6
therefor
a number multipled by 6 will be twice as large as a number multiplied by 3

or
if you double a number multiplied by 3, you wil get the same original number multiplied by 6
