Answer:
405
Step-by-step explanation:
Since
2 : 9 = 90 : X
Then we know
9/2 = X/90
Multiplying both sides by 90 cancels on the right
90 × (9/2) = (X/90) × 90
90 × (9/2) = X
Then solving for X
X = 90 × (9/2)
X = 405
Therefore
2 : 9 = 90 : 405
It looks like we're told that



We use the fact that
is linear to find
. First, we notice that

We also have


So once we find
, we can determine
and
. We have

and using this we find


Then
