Question

calculati: 1,3x2,5-(4,2+8,6):4 2,3x(1,5-0,75)+7,6:2 5,6:0,7-4,5:9x7 (7,1-2,3x2):5+0,5 3,2+2,1x(7,5-2,5x2) ajutoooooooooooooooor va rog,urgenttttttt

Answer 1

1,3x2,5-(4,2+8,6):4 =3,25-12,8:4=3,25-3,2=0,05

2,3x(1,5-0,75)+7,6:2=2,3x0,75+3,8=1,725+3,8=5,525

 5,6:0,7-4,5:9x7 = 8-0,5x7 =8-3,5=4,5

(7,1-2,3x2):5+0,5 =(7,1-4,6):5+0,5 =2,5:5+0,5=0,5+0,5=1

3,2+2,1x(7,5-2,5x2)=3,2+2,1x(7,5-5)=3,2+2,1x2,5=3,2+5,25=8,45
