Answer 2

(1-7/9)x(5,2-0,7)=2/9x4,5=2/9x45/10=5/2=2 1/2=2,5

 

123:10+0,2x6,1=12,3+1,22=13,52

 

(6,5-4,7):(4-2 1/5)=1,8:(4-2,2)=1,8:1,8=1

 

(1 1/2-1 1/3)x2 2/5-0,1=(1 3/6-1 2/6)x12/5-1/10=1/6x12/5-1/10=2/5-1/10=

=4/10-1/10=3/10=0,3

 

(6,25-2 1/2):2 1/7-1=(6,25-2,5):15/7-1=3,75x7/15-1=375/10x7/15-1=

=1,75-1=0,75
