59 26/60

7 2/7

 

Answer 2

5 1/3-1 2/3= 4 4/3-1 2/3 = 3 2/3
3 5/36-2 13/26= 2 41/36-2 13/36 = 28/36 = 7/9
8 1/3-1 4/3= 7 4/3-1 4/3 = 6
c)12 7/12-11/12= 11 19/12-11/12 = 11 8/12 = 11 2/3
10 5/8-7/7/8= 9 13/8-7 7/8 = 2 6/8 = 2 3/4
82 7/60-31 31/60= 81 67/60-31 31/60 = 50 36/60 = 50 3/5
19 3/7-8 19/7= 18 22/7-8 19/7 = 10 3/7
znajdź x 
a)x+1 3/4=7 1/4

x = 7 1/4-1 3/4

x = 6 5/4-1 3/4

x = 5 2/4

x = 5 1/2

b) x-2 3/5=5 4/5

x = 5 4/5+2 3/5

x = 7 7/5

x = 8 2/5

c) 3 3/10-x=1 1/10

-x = 1 1/10-3 3/10

-x = -2 2/10

-x = -2 1/5 /:(-1)

x = 2 1/5

d) 2 3/7+x=1 1/10

x = 1 1/10-2 3/7

x = 11/10-17/7

x = 77/70-170/70

x = -93/70

x = -1 23/70

e) x-4 7/9=7 8/9

x = 7 8/9+4 7/9

x = 11 15/9

x = 12 6/9

x = 12 2/3

f)5 3/8-x=22 7/8

-x = 22 7/8-5 3/8

-x = 17 4/8  /:(-1)

x = -17 1/2
