Answer 2

7-4/5:21/2=

=6i1/5:21/2=

=31/5razy5/2=

=31/2=

=15i1/2      

 

11/4x13/5-(0,6-0,55)=

=11/4x13/5-(-0,05)=

=143/20+5/100=

=715/100=5/100=

=720/100=

=7i20/100=

=7i1/5

 

1/2x2/3-1/4=

=1/2x2/3-1/4=

=1/3-1/4=

=4/12-3/12=

=1/12

 

4,5x2+0,4x5=

=9+2=

=11                       

Answer 3

7-4/5:2 1/2=7-4/5x2/5 =7-8/25=6 17/25

 

1 1/4x1 3/5-(0,6-0,55)=5/4x8/5-0,05=2-0,05=1,95
