Missed it by thatttttt much, he said holding his thumb and forefinger very close together.

3 times 12 is 36, not 48.

Besides that, you have your fraction upside-down, 108 divided by 52 is greater than one. And so is 96 divided by 52, hence:

Now substitute back:

I'll let you do that arithmetic. Let me know what you discover about the value of
