Explicație pas cu pas:
1 × 2 × 3 × a = 24
6 × a = 24
a = 24 : 6
a = 4
_____
b × 2 × 5 = 40
b × 10 = 40
b = 40 : 10
b = 4
_______
27 : 3 : 3 × d = 6 × 4
9 : 3 × d = 24
3 × d = 24
d = 24 : 3
d = 8
______
c : 2 : 3 = 5
c : 2 = 5 × 3
c : 2 = 15
c = 15 × 2
d = 30
________
e : 8 + 2000 = 2003
e : 8 = 2003 - 2000
e : 8 = 3
e = 3 × 8
e = 24
_________
