Jessica B's Scribe Post

In class today Mr. Jerema gave us questions.
He wrote on the board :
- 1/2 of 36 =
- 1/4 of 36 =
- 1/8 of 36 =
- 5/8 of 36 =

To make things simpler, i just switched the question into an easier form.
- 36 divided by (1/2) 2 = 18
- 36 divided by (1/4) 4 = 9
- 36 divided by (1/8) 8 = 4.5

It was easy to find out what 1/4 and 1/8 because 1/4 is just half of 1/2 . so if 1/2 = 18 . Then 18 divided by 2 = 9 (1/4) . Then 1/8 is half of 1/4 . So 9(1/4) divided by 2 = 4.5 (1/8).

The 5/8 question was harder but you have to make it into a simpler form .
5/8 don't go nice together so you make it into 4/8 . Since 4/8 is another way of saying 1/2 , you get the answer that you got for the first question which was 18 .
Then , since you only have 1/8 left , again you just get the answer you got for the third question , which was 4.5 .

So basically , you're just adding question 1 & 3 together to get question 4 .
So the answer is (18 + 4.5 =) 22.5 .
