Answer 2

1)(2$frac{7}{20}$+5.77):а

2$frac{7}{20}$=2.35

2.35+5.77=812

а=14

812:14=58

2)(52$frac{4}{5}$-7.3):b

52$frac{4}{5}$=52.8

52.8-7.3=45.5

b= 26

45.5:26=1.75

3)2.1:a+17$frac{2}{5}$*0.8

17$frac{2}{5}$*0.8=13.92

a=35

2.1:35=0.6

13.92+0.6=14.52

4)0.78*18-44$frac{4}{25}$:b

0.78*18= 14.04

b=48

44.16:48=0.92

14.04+0.92=14.96
