Question

9/20 - (13/16 - 11 /12) : 25/24

Answer 1

{(9/20) -(13/16 - 11/12)} / (25/24)
={(9/20) - (156/192 - 176/192)} / (25/24)
={(9/20) - (-20/192)} / (25/24)
={(9/20) + (5/48)} / (25/24)
={(108/240) + (25/240)} / (25/24)
={133/240} / (25/24)
=(133*24) / (40*25)
= 3192 / 1000
=399/125
=(375/125) + (24/125)
= 3 24/125
