Change the mixed numbers to improper fractions.
Then invert the second fraction and multiply.

16/5 * 3/8 = Cross-divide the 16 and 8.
2/5 * 3/1 = 6/5 Change to a mixed number.
= 1 1/5

3 1/5 by 2 2/3
16/5 by 8/3
16/5 by 3/8
cross multiply.....
6/5
simplify....
1 1/5





3 1/5 divided by 2 2/3 first you multiply the 3 by the bottom of the fraction (the 5) which is 15 then you add the number on top (the 1) and write it over 5. so 16/5 right? do the same with the other number, and you should get 8/3. now you need to flip the second number (the 8/3) because you are dividing. then you cross multipy and you should get 6/5. but simplest form measn you need to write it as 1 1/5.

3 1/5 divided by 2 2/3= (change to improper fraction)
16/5 divided by 8/3= 16/5 times 3/8 (reverse last number to multiply; cancel out 8 and 16)
Becomes 2/5 times 3/1=(multiply across, numerator and denominator)=6/5 or 1 1/5
