Explicație pas cu pas:
a)
x = 4
b)
x = 1/6 : 3/4 = 1/6*4/3 = 4/18 = 2/9
c)
x = 1/10 : 1/4 = 1/10 *4/1 = 4/10 = 2/5
d)
3/2 *x = 5/6
x = 5/6 : 3/2 = 5/6 * 2/3 = 10/18 = 5/9
e)
11/2 * x = 78/5
x = 78/5 : 11/2 = 78/5 * 2/11 = 156/55
f)
x * 13/3 = 33/4
x = 33/4 : 13/3 = 33/3 * 3/13 = 33/13
g)
x = 3*3/4 = 9/4
h)
5/6 : x = 5/3
x = 5/6 : 5/3 = 5/6 * 3/5 = 1/2
i)
x : 26/5 = 5/8
x = 5/8 * 26/5 = 26/8 = 13/4
j)
15/8 : x = 9/8
x = 15/8 : 9/8 = 15/8 * 8/9 = 15/9 = 5/3
