Answer 1

a)x*4/7=9/11 /:4/7
x=9/11:4/7
x=9/11*7/4
x=1.43
b)x:6/13=4/9 /*6/13
x=4/9*6/13
x=24/117

 

 c) 5.2(7 )

 

 

Answer 2

a)

 x * 4/7 = 9/11

x = 9/11 : 4/7

x = 9/11 * 7/4

x = 63/44

x = 1 i 19/44

 

b)

x: 6/13 = 4/9

x = 4/9 * 6/13

x = 8/39

 

c)

x: 3 i 1/6= 1 i 2/3

x = 1 i 2/3 * 3 i 1/6

x = 5/3 * 19/6

x = 95/18

x = 5 i 5/18
