Question

Is 9r+16=π/5 a literal equation?

Answer 1

The given equation is

   $\rightarrow 9r+16=\frac{\pi}{5}$

The value of π is 3.14 or $\frac{22}{7}$ that is a fixed Value.

   $\rightarrow 9r +16=\frac{3.14}{5}\\\\9r+16=0.628\\\\9r=0.628-16\\\\9r=-15.372\\\\r=\frac{-15.372}{9}\\\\r=-1.708$

So, the given equation is Literal ,because variable value is Known.

Answer 2

That is not a literal equation, because the pi symbol is not a variable, you can do 3.14 divided by 5.
