Will fan and medal if you can help me with the answer and explain how to get it

What is
2 2/3- 3/5?

anonymous · Answer

first, convert 2 and 2/3 to an improper fraction

michele_laino · Answer

hint:
$$2\frac{2}{3} = 2 + \frac{2}{3} = \frac{8}{3}$$

anonymous · Answer

so take 3 times 2 and add 2, then put it over 3

anonymous · Answer

8/3?

anonymous · Answer

right!

anonymous · Answer

so subtract 3 from 8

anonymous · Answer

5

anonymous · Answer

and put that over 2 again, so your final answer is 5/2

anonymous · Answer

thanks for the help!

anonymous · Answer

no problem! :)

michele_laino · Answer

sorry, I think that we have:
$$\frac{8}{3} - \frac{3}{5} = \frac{{8 \times 5 - 3 \times 3}}{{15}} = \frac{{31}}{{15}}$$
