Problem: (2*1/4 / 3/4) x 2

Solution: (Further details: Pg.485 Exercise 2.5. Question (h)).

(2*1/4 / 3/4) x 2 =

(9/4 x 4/3) x 2 =

(3/4 x 4) x 2 =

3 x 2 = 6.

Question: Where did the 4 come from in (3/4 x 4) x 2 ?

Here is my answer:

*(2 1/4 / 3/4) x 2 =*

2 1/4 = (2x4+1)/ 4 = 9/4

(9/4 / 3/4 = 9/4 x 4/3 = 36/12 = 6/2 = 3/1) x 2 =

2 x 3/1 = (2x1+3)/1 = 5/1

so 5/1

= 5

2 1/4 = (2x4+1)/ 4 = 9/4

(9/4 / 3/4 = 9/4 x 4/3 = 36/12 = 6/2 = 3/1) x 2 =

2 x 3/1 = (2x1+3)/1 = 5/1

so 5/1

= 5

A little bit confused here...

How is my answer different to the solution in the book?

Am I missing something here?

Maybe the rules are different when the denominator is a one prehaps?

Your help is appreciated Thank you
