Question

Oblicz : / - kreska ułamkowa * - znak mnożenia 1i 3/8 : 3/4: 1i 2/9 = ? 12 * a = 13 i 1/3 2 i 2/5 * d = 9 2 i 5/6 : c = 4 i 1/4 Daje naj :D

Answer 1

1 3/8: 3/4 : 1 2/9 =

=11/8:3/4:11/9 =

11/8 * 4/3* 9/11=

33/2 = 16 1/2 (16,5)

 

 

12*a =  13 1/3

a = 13 1/3 :12

a = 40/3 :12

a= 40/3 * 1/12

a=40/36

a=1 4/36

a = 1 1/12

 

 

2 2/5 *d = 9

d = 9:2 2/5

d=9 : 12/5

d = 9 * 5/12

d = 15/4

d = 3 i 3/4

 

2 5/6 :c = 4 1/4

c = 2 5/6: 4 1/4

c = 17/6 :17/4

c = 17/6 * 4/17

c = 4/6

c = 2/3
