I don't understand why 1/2k is equivalent to k/2. Is it that the 1 is inherently there due to the variable in the numerator? That's my guess

Think this way......

Make k equal to 7 in this situation. If you are to replace k/2 with 7 the number would be 7/2. Now look, 7 times 1/2 is 7/2 and 7 divided by 2 is 7/2.

I hope this helps you (I'm not that good at explaining lol)

Yeh k is the variable, 1/2 k is the correct answer so 1 is the missing number of where k is.

The other correct answer k divided by 2, it's asking you What's divided by 2 that gets you to the answer of 1?. Well... 2 x 1 = 2 so... 2 divided by 2 = 1.

It's the same because it gets you to the same answer of 1.
