(a)
Barrel : Tank : Jar
1 : 4 : 12
(b)
Percentage of water that a barrel can hold as compared to a tank
=
14 x 100%
= 25%
(c)
Volume of 1 tank
= 4 x 5
= 20 ℓ
Volume of 4 tanks
= 4 x 20
= 80 ℓ
(d)
Volume of 1 jar
= 3 x 20
= 60 ℓ
Volume of 3 jars
= 3 x 60
= 180 ℓ
Answer(s): (a) 1 : 4 : 12; (b) 25%; (c) 80 ℓ; (d) 180 ℓ
