Answer 2

actually this is a mathematical work

69)39/4+23/6-187/12

=(117+46-187)/12

=-24/12

=-2

70)29/12+15/4-22/3+25/6

=(29+45-88+50)/12

=36/12

=3

71)60/3=2

therefore

15-2

=13

to get 15,

13+2=15

72)28/3-25/6

(56-25)/6

31/6

=5.1666666667

73)17/20 and 21/25

LCM, of 20 and 25

=17/20×5/5=85/100

=21/25×4/4=84/100

therefore,

85/100>84/100

=17/20 is greater than 21/25
