Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2?

Answers

Because 1/2 of 6 =1/3 and 1/2×1/3=1/6

The number 3 can be expressed as a fraction 3/1. If we multiply the fraction 1/6 by 3/1 we get:
1/6 x 3/1 = (1 x 3)/(6 x 1)
(1 x 3)/(6 x 1) = 3/6
Now just simplify the fraction:
3/6 = 1/2
