e) 13/18 - 5/36 - (25/72 - 1/24)​

Answer 1

a) 5/6 + 2/6 - 1/6 = 7/6 - 1/6 = 6/6 =1

b) 55/60 + 48/60 - 50/60 = 103/60 - 50/60 = 53/60

c) nu știu

d) 220/300 - 90/300 + ( 28/100 - 3/100 )

220/300 - 90/300 + 25/100

130/300 +75/300

205/300

e) 26/36 - 5/36 - ( 50/144 - 6/144 )

26/36 - 5/36 - 44/144

21/36 - 44/144
