k = 5.25

Step-by-step explanation:

y is directly proportional to x

y∝x

y = kx where k is the constant

if y is 84 and x is 16,

84 = 16k

k = 84/16 = 5 4/16 = 5.25

k = 5.25

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
