I am comlpetley lost at how to begin to solve this problem
here is the question
4/3 = 8
-
b
the way it is written in the book is 4/3 divided by b equals 8
:
First of all let's deal with:
4%2F3
----
b
:
Remember when you divide fractions you invert the dividing fraction & multiply
b is not a fraction however we can write it
4%2F3
----
b%2F1
:
Invert the dividing fraction and multiply:
4%2F3*1%2Fb = 4%2F%283b%29
:
Getting back to the equation:
4%2F%283b%29 = 8
:
Multiply both sides by 3b; this gets rid of the fraction
4 = 8(3b)
:
4 = 24b
:
b = 4/24
b = 1%2F6
:
Substitute 1/6 for b; following the rules of fractions and you will see that
4/3 divided by 1/6 = 8

How about this, did I shed any light on this problem for you?
