Question

20 - ( 3 1/6 + 2 3/4 ) = ?

1 5/6 + ( 3 - 1 7/10) = ?

Answer 1

20 - ( 3 1/6 + 2 3/4 ) = 20 - (3 2/12 + 2 9/12) = 20 - 5 11/12 = 14 1/12

1 5/6 + ( 3 - 1 7/10) = 1 5/6 + 1 3/10 = 1 25/30 + 1 9/30 = 2 34/30 = 3 4/30 = 3 2/15

Answer 2

20-(3 1/6 +2 3/4) = 20-5 11/12= 14 11/12

1 5/6+(3-1 7/10) = 1 5/6+ 1 3/10= 1 50/60+ 1 18/60= 3 8/60= 3 2/15
