Five notebooks cost $4.65. what is the price for two
!

Okay so if 5 notebooks equals $4.65 and you want to find the cost of two I suggest finding the cost of one and then multiplying it by two.

so
5 notebooks = $4.65
1 notebook = $?

How do you get from 5 to 1? you divide by 5. now whatever you do to one part of a fraction, you need to do the same to the other. You need to divide the $4.65 by 5.

$4.65/5=$0.93

So 1 notebook is $0.93
2 notebooks equals twice that ($0.93 × 2) which is $1.86

The cost of two notebooks is $1.86

You can cross-multiply to find the answer.  stands for the unknown price of 2 notebooks.
5 notebooks/$4.65 = 2 notebooks/
you multiply 5 and x & 2 and 4.65, so:
5x = (2)(4.65)
5x = 9.30
then, you divide 5 on both sides, to get the x alone, so:
x = 9.30/5
so the answer is $1.86 for 2 notebooks. 

Then why is the question on here if you know the answer
