Вычислить значения выражения: 2) (40/63-8/21):2+1 9/16*1 3/5+2 3/8:3/4.

lollylolly (40/63-8/21):2+1 9/16*1 3/5+2 3/8:3/4 = 5 50/63
1) 40/63-8/21=40/63-24/63=16/63
2) 16/63:2=16/63*1/2=8/63
3) 1 9/16*1 3/5=25/16*8/5=5/2
4) 2 3/8:3/4=19/8*4/3=19/2*1/3=19/6
5) 8/63+5/2=16/126+315/126=331/126
6) 331/126+19/6=331/126+399/126=730/126=365/63=5 50/63

irchykzem (((40/63)-(8/21))/2)+((19/16)*(13/5))+((23/8)/(3/4)) = ((0,63-0,38)/2)+(1,19*2,6)+(2,88/0,75)=(0,25/2)+3,09+3,84=0,13+6,93=7,06
