Question

oblicz: 2 i 1/3 + 3/4 : 1/2 2 i 1/5 : 11/20 + 3/4 : 1 i 1/2 4 i 1/5 : 5/6 - 1 i 1/5 x 1 i 2/3 iloraz liczb 2 i 1/5 oraz 3 i 1/3 zwiększ 100 razy iloraz liczb 2 i 1/5 oraz 3 i 1/3 zwiększ o 100

Answer 1

2  1/3 + 3/4 : 1/2 =
2  1/3 + 3/4 x 2/1 =
2  2/6 + 9/6 =
2  11/6 =

3  5/6

 

2  1/5 : 11/20 + 3/4 : 1  1/2 =

11/5 x 20/11 + 3/4 x 2/3 =

4 + 1/2 =

4  1/2

 

4  1/5 : 5/6 - 1  1/5 x 1  2/3 =

21/5 x 6/5 - 6/5 x 5/3 =

126/25 - 2 =

5  1/25 - 2 =

3  1/25

 

2 : 1/5 =

2/1 x 5/1 =

10

10 x 100 =

1000

 

3 : 1/3 =

3/1 x 3/1 =

9

9 x 100 =

900

 

2 : 1/5 =

2/1 x 5/1 =

10

10 + 100 =

110

 

3 : 1/3 =

3/1 x 3/1 =

9

9 + 100 =

109
