Hey mate!!
Since, proportionality sign indicates the relation between two ratios.
Therefore,
21:15 :: 84:x
21/15 = 84/x
On simplifying we get that,
x = 60
Hope it helps!!

Answer:
60 is the answer.
Step-by-step explanation:
21 : 15 :: 84 : X
= 21/15 = 84/X
NOW WE WILL DO CROSS-MULTIPLICATION.
SO,
21 × X = 15 × 84
X = 15 × 84 / 21
X = 1260 / 21
X = 60
