Answer 1

1. 0,9 - 40/100 + 8/5 = 0,5 +8/5= 2,1
2. 4,85 - 65/100 + 7/10= 4,2 + 7/10= 4,9
3. 55/100+ 0,45 - 3/5= 0,4
4. 23/4 -2,5 +24/100= 3,49
5. 30/100 +2,7 -14/5= 0,2
6. 35/100 + 6/5 - 0,8 = 0,75
7. 2,47 + 13/10 - 85/100 = 2,92

Answer 2

1). 0,9=9/10
40%=40/100 ÷2/2 =20/50 ÷2/2= 10/25÷5/5=2/5
1 3/5=8/5 =9/10-2/5 +8/5 = kpk 10
9/10x2/2 = 18-4+16 = 14+16=30/20 ÷2/2 =15/10÷5/5= 3/2 atau 1 2/1
