What is one third the difference between 3/4 and 2/3?
Ivan

Answer:

One third the difference between 3/4 and 2/3  is (\frac{1}{36} )

Step-by-step explanation:

One third the difference of A and B  =  \frac{1}{3} \times (A-B)

Here, as given in the question:

A = \frac{3}{4} , B = \frac{2}{3} \\\implies A  - B =  \frac{3}{4} - \frac{2}{3}\\=(\frac{3 \times 3 -2 \times 4}{12})  = (\frac{9-8}{12} ) = (\frac{1}{12})\\ \implies  A  - B =  (\frac{1}{12})

Now, one third of the difference is :

(\frac{1}{3}) \times (\frac{1}{12}) =   (\frac{1}{36})

Hence, one third the difference between 3/4 and 2/3  is (\frac{1}{36} )
