Question

Oblicz¾ wartości wyrażenia:
(2,2-1⅔)×0.9=
2×3,5+½×0,25=
4,5×1⅔-3,75=
10-¹⁰/₂₇÷⅚=

Answer 1

(2,2-1⅔)×0.9= (22/10-5/3)*9/10 = (66/30-50/30)*9/10=16/30*9/10 = 144/300 = 12/25 = 0,48

2×3,5+½×0,25=7+0,125=7,125=7⅛

4,5×1⅔-3,75=45/10*5/3-3,75 = 7,5-3,75 = 3,75

10-¹⁰/₂₇÷⅚=10-10/27*6/5 = 10-4/9 =9 i 5/9
