Question

The Pacific Ocean covers about $46\%$ of Earth. If P represents the surface area of the Pacific Ocean and E represents the surface area of Earth, write an equation for this situation.

Step-by-Step Solution

Answer

Equation for given statement  $P=0.46E$.

Step 1. Variables.

Variables are used in equation to denote arbitrary or unknown value.

P represents the surface area of Pacific Ocean and E represents the surface area of Earth.

Step 2. Use given information and determine the equation.

Pacific Ocean is $46\%$ of earth.

This can be written as:  $P=46\%\mathrm{of}E$

Step 3. Simplify the equation.

$\begin{array}{l}P=46\%\mathrm{of}E\\ P=\frac{46}{100}E\\ P=0.46 E\end{array}$

Hence, the equation for given situation is  $P=0.46E.$
