Question

Proszę o rozwiązanie punktu: c d f.
proszę o pomoc z góry dzięki :)

Answer 1

C)
x + 3 7/12 = 7 4/9
x = 7 4/9 - 3 7/12 = 7 16/36 - 3 21/36 = 6 52/36 - 3 21/36 = 3 31/36
d)
x - 2 5/6 = 1 7/24
x = 1 7/24 + 2 5/6 = 1 7/24 + 2 20/24 = 3 27/24 = 4 3/24 = 4 1/8
f)
9 1/6 - x = 3 1/4
- x = 3 1/4 - 9 1/6
- x = 3 6/24 - 9 4/24 = - 6 2/24 = - 6 1/12
- x = 3 6/24 - 8 28/24 = - 5 22/24 = - 5 11/12
x = 5 11/12

Answer 2

C) 7 4/9 - 3 7/12 = 7 16/36 - 3 21/32 =3 31/36   x=3 31/36
d) 7 1/24 + 2 5/6 = 7 1/24+ 2 20/24= 9 21/23   x=9 21/23
f) 9 1/6 - 3 1/4 = 9 2/12 - 3 3/12= 5 11/12
