Direct proportionality is the type of proportionality where an increase in one quantity or variable causes a corresponding increase in another quantity.
Therefore; y varies directly as x
Hence; y α x
y =k x where k is a constant
if y= 28 and x = 7 , then k = 28/4 =4
hence, y = 4 k
when x = 4, then y= 16

True multiply both sides by 15
25 mg is lighter than 25 cg because mg is 0.001 g and cg is 0.01 g :)
Answer:
