7,13

-------

2,75 - 1 3/5

Answer 1

a)10,6 -4 2/3 + 16 1/15= 10 6/10- 4 2/3 +16 1/15= 10 16/30- 4 20/30+ 16 2/30=26 18/30- 4 20/30= 21 28/30

b)6 1/2 + (3 2/6 - 3/6) : 2 5/6 - 1 3/4= 6 2/4 + 2 5/6 : 2 5/6 - 1 3/4= 6 2/4 + 1 - 1 3/4=  7 2/4- 1 3/4= 5 3/4

c) 7,13           

   ------     =  7,13:1,15=6,2

   2,75-1,6

Answer 2

10,6 -4i2/3  +16i1/15= 10i3/5 - 4i2/3 +16i1/15= 10i9/15- 4i10/15+ 16i1/15= 22 

 

6i1/2 +(3i1/3 -1/2) :2i5/6 -1i3/4= 6i1/2+ (3i2/6 -3/6): 17/6 -1i3/4= 

= 6i1/2 +2i5/6: 17/6- 1i3/4= 6i1/2+17/6* 6/17 - 1i3/4= 6i1/2 +1 - 1i3/4=

= 6i2/4 +1 - 1i3/4= 5i6/4 +1 - 1i3/4= 5 i 3/4

 

 

                7,13                            7,13                7,13

      _______________   =    ____________ = ____________=  7,13 : 1,15 =  6,2
