Question

1. (6,7+5 3/4 ):6/50 = 2.7/10+4 1/5 : 0,1= 3. 3,24 +2 1/2 *1 3/5 = 4.26,09 - [5/6 - 1,5 +(0,25 + 2 1/2 ) : 25 / 56= Pomocyy.!!!!!!!!!!!!!!! daje naj :))

Answer 1

1.

(6,7 +5i3/4) : 6/50 =

(6,7 +5,75) : 0,12 =

12,45 : 0.12 = 

1245 :12 = 103,75 

 

2.

7/10 +4i1/5 : 0,1 =

 0,7 + 4,2 : 0,1 =

 0,7 + 42 = 42,7

 lub

7/10 + 4i1/5 : 0,1=

7/10 + 21/5 : 1/10=

7/10 + 21/5 * 10/1 =

7/10 + 210/5 = 

7/10 + 42  = 42i7/10

 

3.

3,24 +2i1/2 *1i3/5 = 

3,24 + 2,5 * 1,6 =

3,24 + 4 = 7,24

 

4.

26,09- [5/6 -1,5+(0,25 +2i1/2)] : 25/56=

26,09 -[5/6 -1,5+(1/4 + 2i1/2)] : 25/56 =

26,09 -[5/6 -1i1/2 +(1/4 +2i2/4)] : 25/56=

26,09 -[5/6 -1i1/2 +2i3/4] : 25/56=

26,09 -[10/12 -1i6/12 +2i9/12] : 25/56 =

26,09 -[  2i1/12] :25/56 =

26,9/100 - 25/12 * 56/25 =

26i9/100 - 1/3 * 14/1 =

26i9/100 - 14/3 =

26i9/100 - 4 i2/3=

26i27/300 - 4i200/300=

25i327/300 - 4i200/300 =

21 i 127/300
