Question

Rozwiąż równania a) 3/4*y=2 i 1/5 b) 2/3:x=1 i 1/4 c) x:2/5+3 i 1/4

Answer 1

a)

3/4*y=2 i 1/5

y = 2 i 1/5 : 3/4

y = 11/5 * 4/3

y = 44/15

y = 2 i 14/15

 

b)

2/3:x=1 i 1/4

x = 2/3 : 1 i 1/4

x = 2/3 : 5/4

x = 2/3 * 4/5

x = 8/15

 

c)

x:2/5 = 3 i 1/4

x = 3 i 1/4 * 2/5

x = 13/4 * 2/5

x = 13/10

x = 1 i 3/10
