Question 133081
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
{{{(36/10) / (21/10) }}}
{{{ 36/21 }}}
{{{ 12/7 }}}

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 
{{{(28 * 10)/(5 * 21)}}}
{{{ (4 * 10)/(5 * 3) }}}
{{{ (4 * 2) / (1 * 3) }}}
{{{ 8/3 }}}
