5 Times What Equals 100

Decoding "5 Times What Equals 100": A Deep Dive into Multiplication and Beyond

What number, multiplied by 5, results in 100? This seemingly simple question, "5 times what equals 100," opens a door to a fascinating exploration of multiplication, its applications in various fields, and the broader mathematical concepts it connects to. This article will not only answer the question directly but also delve into the underlying principles, practical examples, and related mathematical concepts. Understanding this fundamental arithmetic operation is crucial for anyone navigating the world of numbers, from everyday calculations to complex scientific modeling.

Understanding Multiplication: The Foundation of "5 Times What Equals 100"

Multiplication, at its core, is repeated addition. When we say "5 times what equals 100," we're essentially asking: "What number, added to itself five times, equals 100?" This fundamental understanding is key to grasping the solution and expanding our mathematical comprehension. Think of it like arranging objects in equal rows: five rows of what quantity will give you a total of 100 objects?

The equation representing "5 times what equals 100" can be written as:

5 * x = 100

Where 'x' represents the unknown number we're trying to find.

Solving the Equation: Finding the Answer

To solve for 'x', we use the inverse operation of multiplication, which is division. We divide both sides of the equation by 5:

x = 100 / 5

This gives us the answer:

x = 20

Therefore, 5 times 20 equals 100.
