Two bricklayers, sam and joe, are working on your house. sam can complete the work in 5 hours, while joe can complete the work in 3 hours. how many hours does the bricklaying take if they work together? fifteen eighths fifteen ninths six eighths four thirds

 Your equation is 1/5 + 1/3 =1/x To solve you have to find the common denominator which is 15 So (1/5)3 and (1/3)5

                                          = 3/15+5/15=8/15

                                                  8/15=1/x now cross multiply

                                                   =15/8

This is the answer I got.

d is correct
