first add the height of the cd player and amplifier:

4 5/8 + 6 3/4=X

4 5/8 + 6 6/8=X

10 11/8 =X

X= 11 3/8

Next subtract this height from the shelf height:

12 1/2 – 11 3/8 = X

12 4/8 – 11 3/8 = X

Your answer:

X= 1 1/8″

start by changing the denominators so that they are all the same, so finding the lowest common denominator (LCD).

you have 1/2, 5/8, and 3/4. all of those numbers can be changed to “8”

so 1/2*4/4 is 1*4/2*4 = 4/8. the cabinets are also 12 4/8″ tall

then 5/8 is fine the way it is, so the CD’s remain 4 5/8″ high

then 3/4 is multiplied by 2/2, so 3*2/4*2 = 6/8, so the amp is 6 6/8″ high

then you add the amp and the CD height:

=6 6/8 + 4 5/8

=10 11/8

obviously you can get another whole number out of 11/8, so 11/8 = 1 3/8 (8+3=11)

so your total height for those two objects is 11 3/8 (10 + 1 3/8)

then you subtract that total from the hight of the shelves;

12 4/8 – 11 3/8 = 1 1/8

so you have 1 1/8″ left above the CD player.

4 5/8 + 6 3/4

4 5/8 + 6 6/8

10 11/8 (reduces to 11 3/8)

12 1/2 – 11 3/8

12 4/8 – 11 3/8

your answer is 1 1/8 inches

I’m not going to do it for you, but I’ll make it easier- the key is that all the fractions can be divided into eigths- so 1/2 becomes 4/8, 5/8 stays at 5/8, and 3/4 becomes 6/8. Should be easy to work out from there because you can add all the fractions together.

you gotta find a common denominator. lets make it 8

12 1/2 – (4 5/8 + 6 3/4) = 12 4/8 – (4 5/8 + 6 6/8)

12 4/8 – 11 3/8 = 1 1/8

Add the player height and amplifier height.

first, your fractions need to be the same denominator. in this case it will have to be in 8’s.

3/4 = 6/8

now add 4 5/8 and 6 6/8 = ?( hint 5/8 + 6/8 = 1 3/8)

now subtract your total inches from the total space – 12 1/2

If you cannot get it from there and no one else gives you the answer, email me.

6 3/4= 6 6/8

+ 4 5/8

———————–

10 11/8= 11 3/8 (that’s because 8/8=1)

12 1/2 = 12 4/8

– 11 3/8

——————————

1 1/8
