8*1 2/3 and Times 7*3 1/5

13 1/3, 22 2/5

Step-by-step explanation:

It'll be easier if you put both of the mixed fractions into improper fractions, so:

1 2/3 - --> 3 x 1 + 2 = 5 - --> 5/3

3 1/5 - --> 5 x 3 + 1 = 16 - --> 16/5

Now if you want to write it down, but 8/1 to make it easier to work out.

8/1 x 5/3 = 8 x 5/3 x 1 = 40/3 or 13 1/3

7/1 x 16/5 = 7 x 16/1 x 5 = 112/5 or 22 2/5

I can get more descriptive, but this is the layout. Hopefully this makes sense.
