178/8 can be reduced to 89/4.

1.8 + 0.7 can be reduced to 2.5 which can be written as 5/2.

(89/4) / (5/2)  =  (89/4) x (2/5)                  (change from division to multiplication)

                        =  (89/2) x (1/5)                  (cancel the 2s)

                        =  89/10  or 8.9
