Będzie naj .. : ^

Answer 1

1)4/5 : x = 2 

4/5 * 1/x = 2

1/x = 2 * 5/4

1/x = 5/2 (odwracamy aby otrzytmac x)

x = 2/5

2)5/4 : x = 1 |*x

5/4 = x 

x = 1 1/4

3)3/2 : x = 1/2 |*2

3 :x = 1 |*x

3 = x 

4) x * 4/7 = 1 |*7/4

x = 7/4

5) x * 7/10 = 1 |*10/7

x = 10/7 

x = 1 3/7  

6) x * 5/8 = 1 |* 8/5

x=8/5

7)10/7 * 21/20 = 3/2 = 1 1/2 

8)1/8 * 4 = 1/2

9)2/3 * 3 = 2
