a) ⅔ · ( 2⅚ + 1 75/100) = 2/3 * (17/6 + 175/100) = 2/3 * (17/6 + 7/4) = 2/3 * (34/12 + 21/12) = 2/3 * 55/12 = 55/18 = 3 1/18
b) ( 4 ⅞ - 2 5/10) · 1 ⅓ = (39/8 - 25/10) * 4/3 = (39/8 - 5/2)* 4/3 = (39/8 - 20/8) * 4/3 = 19/8 - 4/3 = 19/6 = 3 1/6
c) 2 ⅔ : ( 1 ⅞ + 2 2/10 ) = 8/3 : (15/8 + 22/10) = 8/3 : (75/40 + 88/40) = 8/3 : 163/40 = 8/3 * 40/163 = 320/489
d) 1 ⅘ : ( 8 13/25 - 1 5/10) = 9/5 :(213/25 - 15/10) = 9/5 : (426/50 - 75/50) = 9/5 : 351/50 = 9/5 * 50/351 = 90/ 351= 30/117
