Question

1)4+1,8)+2,2= 1,6+(5+3,4)= (2,41+13)+4,59= 2)0,3+(1,7+2,5)= (3,8+6)+4,2= 12,25+(8+3,75)= 3) 8,3+(2,7+8)= 10,2+(1,7+4,8)= (46,3+18)+4,7=

Answer 1

1)(4+1.8)+2.2 = 5.8+2.2=8
2)1.6+(5+3.4)=1.6+8.4=10
3)(2.41+13)+4.59 = 15.41+4.59=20

4)0.3+(1.7+2.5)=0.3+4.2=4.5
5)(3.8+6)+4.2=9.8+4.2=14
6)12.25+(8+3.75)=12.25 + 11.75 =24

7)8.3+(2.7+8)=8.3+10.7=19
8)10.2+(1.7+4.8)=10.2+6.5=16.7
9)(46.3+18)+4.7=64.3+4.7=69
