The value of g = 144 solved by using direct proportion.
<h3>What is a direct proportion?</h3>Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value. It is represented by the proportional symbol, ∝.
Given that,
h = , j =
, g = 4
g ∝ hj
g = khj
where k is a constant.
4 = k××
k = 24
Also given that,
g = ? , h =2, j = 3
g = khj
g = 24×2×3
g = 144
Hence, The value of g = 144.
