if ?/100 = o.2 then ?=
To find the value of ?, you can set up the equation from the given information ?/100 = 0.2.
To solve for ?, multiply both sides of the equation by 100:
\[
\frac{?}{100} \times 100 = 0.2 \times 100
\]
This simplifies to:
\[
? = 20
\]
So, ? = 20.
To solve for ?, multiply both sides of the equation by 100:
\[
\frac{?}{100} \times 100 = 0.2 \times 100
\]
This simplifies to:
\[
? = 20
\]
So, ? = 20.
