You want to place a towel bar that is 10 1⁄4 inches long in the center of a door that is 26 1⁄3 inches wide. How far should you place the bar from each edge of the door?
put the on the same denominatior.
So it's 26 4/12 and 10 3/12.
Substract 10 3/12 from 26 4/12 (4/12 - 3/12 = 1/12)
You'll have 16 1/12 now divide it by 2 (because it's the total measurement that's free on the door (sorry if it's not clear...)).
Note: 2 is in reality 2/1
When you divide a fraction, you multiplie by the inverse.
So you keep the 1/12 and you multiply it by the invers of 2/1...1/2
1/12 * 1/2 = 1/24
Now add the 16 divide by 2 and you'll have you have your answer.
8 1/24
Just do this [(26 + 1/3) - (10 + 1/4) ] / 2 =
[79/3 - 41/4 ] / 2 =
[79*4 - 3*41] / [12 * 2] =
[316 - 123] / 24 =
193/ 24 =
8 + 1/24 inches from the edge
