Qs.10)first you change the hours into minutes than after you got the answer you do a fraction then you make it small digit

1 hour = 60 mins
2 hour = X(120)

do a cross multiply and it was 2 times 60 =120
so after that you do fraction of it=(20/120)
than you make it small then you divide by 20 and you will get =(6/1) and that's the answer just =6
