Question

Which of the following is a constant?

$5y,x,3.14,\frac{3}{2}x$

• A. $5y$
• B. $x$
• C. $3.14$
• D. $\frac{3}{2}x$

Answer 1

The correct option is C $3.14$

A constant has a fixed value. Here 3.14 has a fixed value, so it is a constant.

$5y,x\&\frac{3}{2}x$ have variables in it, $y,x\&x$ respectively. So they are not constants.
