Answer 1

5 1/3 : 2 2/15 - ( 1 3/4 - 6 1/4 *1/6)=5 1/3 : 2 2/15 - (1 3/4 - 25/4 * 1/6 )=
16/5 : 32/15 - (7/4 - 25/24) = 16/5 : 32/15 - ( 42/24-25/24)=
16/5 : 32/15 - 17/24 = 16/5 * 15/32 - 17/24 = 240/160 - 17/24 = 24/16 - 17/24 = 72/48 - 34/48 = 38/48 = 19/24
(1 1/8 + 3 5/6 * 5/23) - (4 1/3 : 26 + 1 1/4) = ( 9/8 + 23/6 * 5/23) - (13/3 : 26/1 + 5/4)=
(9/8+115/138)-(13/3*1/26 + 5/4)= (9/8 + 5/6)-(13/78+5/4)=(27/24+20/24)-(1/6+5/4)=
47/24-(2/12+15/12)=47/24 - 17/12 = 48/24 - 34/24= 14/24 = 7/12
