Answer 1

a)1:(1·30/11-15/10)+125/1000·9/6=
1:(135/110+9/48)=1:747/528=528/747

b)101/10:(101/30·333/130):13/9=101/10·30/101·130/333·9/13=1270/1443

c)484/100·(1/1089+3/4·180/60)=484/100·(1/1089+9/4)

Answer 2

a) 1:(1 :11/30-1,5)+(0,5)³:0,(6)=
1:(1×30/11-15/10)+5³/10³ : 6/96=

1:(30/11-15/10)+125/1000×9/6=

1:(300-165)/110+1125:6000=

1:(135/110+9/48)=

1:747/528

=528/747

b) 10,1:[(6/5+13/6)×(21/10+6/13):1,(4)=
101/10:[(36+13×5)/30]×[(21×13+6×10)/130):13/9=

101/10:[(36+65)/30]×[(273+60)/130):13/9=

101/10×30/101×130/333×9/13=

=1270/1443

c) 4,84×[0,(03)]²+(4/3)^-1:[37/3×9/4-5,5×9/2]

484/100×[(1/33)²+3/4×(101/4-494/200)=

484/100×(1/1089+3/4×(101/4-494/200)=

121/25×1/1089+3/4×11/200=

121/(25×1089)+33/800=

121/27225+33/800=
