[29/8 + 1/3] : 2/3



{[(15/60 -20/60 ) * 8 -3\10 ]:3\5 } *2\9

Answer 1

[29/8 + 1/3] : 2/3 = [87/24 + 8/24] : 2/3 = 95/24 * 3/2 = 95/8 * 1/2 = 95/16= 5 15/16

{[( 15/60 - 20/60) * 8 - 3/10] : 3/5 } * 2/9 = {[ -5/60 * 8 - 3/10 ] : 3/5 } * 2/9 =
= {[ -40/60 - 3/10] : 3/5} * 2/9 = {[-40/60 - 18/60] : 3/5} *2/9 = {-58/60 : 3/5} * 2/9 =
= {-58/60 * 5/3} * 2/9 = {-58/12 * 1/3} * 2/9 = -58/36 * 2/9 = -58/18 * 1/9 = -58/162 =
= - 29/81
