Answer 1

2½*(0,15+8/15:4)=5/2*(3/20+8/15*1/4)=5/2*(9/60+8/60)=
=5/2*17/60=17/24
1⅗-(⅝*0,8+1⅗):2=1,6-(0,125*0,8+1,6):2=1,6-1,7:2=(-0,05)
1,6-(1⅗+4/5)=1,6-(1,6+0,8)=1,6-2,4=(-0,8)
3⁵/₆+4⁴/₉=23/6+40/9=69/18+80/18=149/18
42,3+0,65=42,95
8,3-3,532=4,768
7i½*2⅗=15/2*13/5=39/2=19 I 1/2
2,89*6,9=19,941
4⅘:1⁵/₇=24/5*7/12=14/5=2,8
59,569:6,34= 9,395
