We have a bookshelf that's 42 inches long.
00:07
This is 42 inches.
00:10
Each book is half an inch.
00:13
So we need to figure out how many books are going to fit on that.
00:17
So we're going to take 42 and we're going to divide it by, oops, that's one and a half inches.
00:22
Let me take that back in.
00:26
So that's one and a half inches.
00:28
So 42 divided by one and a half.
00:32
So that's really 42 divided by three halves.
00:35
So 42 over 1, division becomes multiplication, and we flip our second number or take the reciprocal.
00:44
We multiply straight across, so that's 84 over 3.
00:48
So that gives us 28...
