Question

Which is the coefficient of ‘f ’ in the expression 7f – 16?

  1. 7    
  2. 16    
  3. 10    
  4. 6    

Hint:

This is an algebraic expression. An algebraic expression consists of two components: a variable and a constant. A variable is a quantity that doesn’t have any fixed value. It takes value according to the conditions. It is denoted by the alphabet. A constant is a quantity with a fixed value. In this question, we are given an expression. We are asked to find the coefficient of the variable.

The correct answer is: 7


    The given expression is 7f – 16.
    There is one variable in the above equation. The variable is ‘f’. We are asked to find coefficient of that variable.
    Coefficient is the quantity that is multiplied to the variable. In the above expression only the first term has the variable. And we can see the number 7 is multiplied to the variable.
    So 7 is the coefficient of the variable ‘f’.
    Therefore the option which is '7’, is the right option

    We should be careful about if there are operations that can change the coefficient. We need to simplify the expression before telling the coefficient.
