You can put this solution on YOUR website!
Let's do two of these. You can do the other ones once you have the method figured out.

5 3/5 to 2 1/10
18/5 to 21/10
36/10 to 21/10

can it be written as a decimal? Yes, but that is not what they asked for as a solution, So I would not do that in this problem.
28/5 x 10/21 (i reduced)=
9/5 x 2/7= 18/7 = 2 4/7 <-- check again 28/3 is not 9. You have the correct method. You just made an arithmetic error. don't worry, it happens to us all.
28/5 * 10/21
