Did you mean the following for the problem:

10) perform the indicated operations
3 and 3/4 (divided by ) 1 and 3/8

.
3 3/4 - 1 3/8
.

15/4 (divided by ) 11/8= 30/11 =(after rounding it should be 2.73) that's how it suppost to be and look

You use the inverse of the divisor, and then multiply.

15/4 divided by 11/8 = 15/4 * 8/11 = 30/11

Even though I am not drawls, yes, that is the way it is supposed to be.

I hope this helps. Thanks for asking.

Thank you Psydag
