E. [tex]0.4 \cdot 84[/tex]

Answer :

On calculating, the 40% of 84 is found to be 33.6.

What is an expression? What is a expression? What is a mathematical equation?

  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is that to find the 40% of 84.

Assume that the 40% of 84 is equivalent to [x]. Then, we can write -

x = (40/100) x 84

x = 4/10 x 84

x = 8.4 x 4

x = 33.6

Therefore, on calculation, the 40% of 84 is equivalent to 33.6.
