9
27/9 = 3
54/9 = 6
81/9 = 9
The expression is equivalent to 49/8.
5d=470:
in this case we have to divide both sides by 5:
d=94
8a=47:
in this case we have to divide both sides by 8:
a=5.875
as a general rule, if you want to find out a value of a in
ab=c
you have to divide both sides of the equation by b (if it's not zero); then you will have left:
a=c/b
and if you calculate c/b, this will give you the answer
5 = 50
8 = 80
because:
20:2= 10 so 1 shirt will collect 10
