помогите вычислить плис

(((3+7/25) + 2,72) 5/24)/(15/16 (3+3/4) - 2/9) -((0,36 + 0,224/0,35) 5)/((5,85

1) ((3+7/25) + 2,72) 5/24) = (3+7/25) 5/24 + 2,72 5/24 = 82/25 5/24 + 272/
/100 5/24 = 82 5/(25 24) + (272 5)/100 24 = 410/600 + 1360/2400 = 1640/

2) 15/16 (3+3/4) = 15/16 15/4 = 15/16 4/15 = (15 4)/(16 15) = 4
3) 4/1 - 2/9 =36/9 - 2/9 = (36-2)/9 = 34/9
4) 5/4 34/9 = 5/4 9/34 = (5 9)/(4 34) = 45/136

/100 + (0,224/0,7) = 108/100 + (224/1000 7/10) = 108/100 +(224/1000 10/7)=
= 108/100 + ((224 10)/(1000 7)) = 108/100 + 32/100 = (108 + 32)/100 = 140/
