Varies inversely :
f(x) = k/x
There is always a constant of variation , k to solve for using the given information. when x = 0.4 ; f(x) = 0.2
0.2 = k/0.4
0.2(0.4) = k
0.08 = k
final equation : f(x) = 0.08/x
when x = 1.6
f(x) = 0.08/1.6
f(x) = 0.05

<u>Step-by-step explanation:</u>
While translating the problems into mathematical expression or mathematical expression in English, Kind of Expression can be used. Mostly in the algebraic parts.
Quotient: It represents that one value is divided by the another value. It is also known as the ratio.
i.e: .
Product: It means multiplying either a known value and unknown variables or both unknown variables.
i.e.: 8b.
Sum: It means adding either a known value and unknown variables or both unknown variables.
i.e.:
