Normally * and / are done before + and -. However,1 and 5/16 is taken to be one complete number, as well as 2 and 7/8. Therefore, the terms 21/16 and 23/8 is a division problem.
(21/16)/(23/8)=21/16*8/23=21/2*1/23=21/46.Normally, we are instructed to leave the answer as a fraction unless instructed otherwise.Also, if an answer other than a fraction was asked for there would be a note of how many places to the right of the decimal point were needed. Therefore,my best answer would be 21/46.
