Answer 1

16 : x::17: 51

16×51= 17x

16×51/17=x

16×3=x

48=x

Answer 2

16:?::17:51

Let ?=x

Then Proportion can be Written as

16:x::17:51

Proportion Sign=::

MEANS Ratio Left Side is Equavalent to Ratio Right Side.

Then Proportion

16:x=17:51

We know a:b=a/b

Then

$\frac{16}{x} = \frac{17}{51} \\ \\ 16 \times 51 = 17x \\ \\ 17x = 816 \\ \\ x = \frac{\cancel{816}}{\cancel{17}} \\ \\ x = 48$

We know x =?

?=48

Then

$\boxed{\mathbf{16:48::17:51}}$
