Answer 1

a) 1,35:1,5+5,4:1,35+0,4×0,2×(4,4-1,37)=13,5:15+5,4:1,35+0,4×0,2=0,9+540:135+0,08=0,9+4+0,08= 4,9+0,08=4,98

b) (3,5:10+11,37×10)-(0,057+3,218+3,218×2,5)=(0,35+113,7)-(0,057+3,218+8,045)=114,05-(3,275+8,045)=114,05-11,320= 103,730

c)5,2×(4,5:0,9+1,25)×1,4-(2,123+5,837)×4=5,2×(45:9+1,25)×1,4-7,960×4= 5,2×(5+1,25)×1,4-31,84=5,2×6,25×1,4-31,84= 32,5×1,4-31,85=45,5-31,85=13,65
