Explicație pas cu pas:
d)
11/5 + x = 22/7
x = 22/7 - 11/5 = 110/35 - 77/35 = 33/35
g)
x - 8/3 = 1/24
x = 1/24 + 8/3 = 1/24 + 64/24 = 65/24
d)
5/7 *x = 1
x = 1 : 5/7 = 1*7/5 = 7/5
h)
1/2 *x = 2
x = 2 : 1/2 = 2*2/1 = 4
c)
35/2 : ? = 7/2
? = 35/2 : 7/2 = 35/2 *2/7 = 5
f)
226/125 : ? = 339/125
? = 226/125 : 339/125 = 226/125*125/339 = 226/339 = 2*113/3*113 = 2/3
c)
x - 8/3 = 1/24
x = 1/24 + 8/3 = 1/24 + 64/24 = 65/24
f)
14/3 + x = 7
x = 7 - 14/3 = 21/3 - 14/3 = 7/3
i)
4 1/7 - 4 x/14 = 0
4 1/7 = 4 x/14
1/7 = x/14
2/14 = x/14
x = 2
