Mr cooper has a piece of a lace trim that is 9/10 inch long. He cut off an 4/5 inch piece. How long is the remaining piece of lace trim?

Respuesta :

First, convert 4/5.

4 times 2              8                                     9/10-8/10= 1/10
 ----------    =   ----------
5 times 2            10
            Hope this helps!                   
I believe it is 1/10. because you need the same denominator so multiply 2 to 4/5. Multiply by 2 on the top and bottom and you should get 8/10. then you subtract 9/10 - 8/10= 1/10.
