Answer:

or

227.12

Answer 2

The correct alternative would be 3861/17

We know that in proporions,

a:b::c:d can be written as

a/b = c/d.

Here, we have to find the unknown term, let it be x.

So, 17:297::13:x

So, 17/297 = 13/x

⇒ 17x = 13*297           [By cross multiplicaton]

⇒ x = 13*297/17

= 227.12

or, 3861/17
