Question

A food company reduced the amount of salt in one of their food products from $700$ milligrams to $630$ milligrams.

What is the percent decrease in the amount of salt in the food product?

Answer 1

Finding the percentage decrease in the amount of salt in the food product:

Definition of percentage:

In percentage, the quantity of anything is stated as though it were a fraction of a hundred.

A fraction of $100$ can be used to express the ratio.

The percentage decrement is found as,

$\text{Percentage =}\frac{\text{final-initial}}{\text{initial}}\text{×100}$

Substituting the final amount as $700$ and the initial amount as $630$ in the above Equation we get,

$$\begin{gathered} \text{Percentage=}\frac{700-630}{630}\text{×100} \\ \text{Percentage=}\frac{70}{630}\text{×100} \\ \text{Percentage=11.11\%} \end{gathered}$$

Hence, the percent decrease in the amount of salt in the food product will be $11.11\%$.
