you switch the division sign to multiply and put 10 and then multiply to get 63 
                                                                           9                                        80  then divide to get your answers
7/8 divide by 9/10

Flip the second fraction =

7/8 divide by 10/9 = 70/72

70/72= 35/36 that is the answer
