Answer 1

10 6/20-4 16/20 =
= 9 + 1 + 6/20 - (4 + 16/20) =
= 9 + 20/20 + 6/20 - 4 - 16/20 =
= 9 + 26/20 - 4 - 16/20 =
= 5 + 10/20 =
= 5 + 1/2 = 5 1/2

10 6/20•4 16/20 =
= 206/20 • 96/20 =
= 103/10 • 24/5 =
= 2472/50 = 49 22/50 = 49 11/25

10 6/20:4 16/20 =
= 206/20 : 96/20 =
= 206/20 • 20/96 =
= 206/96 = 103/48 = 2 7/48
