2 Simple Ways To Calculate 90 Divided By 2

Quick Links :

Performing division is a fundamental arithmetic operation that helps us share quantities into equal parts or groups. Among various division problems, one that is commonly encountered is dividing 90 by 2. This operation is straightforward and can be solved using different methods. In this article, we will explore two simple ways to calculate 90 divided by 2.

Understanding Division

Before we dive into the methods, it's essential to understand what division entails. Division is the process of sharing a certain number of items into equal groups or parts. In the case of dividing 90 by 2, we are essentially splitting 90 items into 2 equal groups.

Method 1: Basic Division

The most straightforward method to divide 90 by 2 is to use basic division. This involves dividing the dividend (90) by the divisor (2).

90 ÷ 2 = 45

As shown above, dividing 90 by 2 results in 45.

Method 1: Real-Life Example

To illustrate this method, let's consider a real-life scenario. Suppose you have 90 cookies that you want to share equally among 2 of your friends. To find out how many cookies each friend will get, you can divide 90 by 2.

90 cookies ÷ 2 friends = 45 cookies per friend

In this example, each friend will receive 45 cookies.

Method 2: Repeated Subtraction

Another way to divide 90 by 2 is to use repeated subtraction. This method involves subtracting the divisor (2) from the dividend (90) repeatedly until you reach zero.

90 - 2 = 88 88 - 2 = 86 86 - 2 = 84 ... 2 - 2 = 0

Counting the number of subtractions, we get:

45 subtractions

Therefore, dividing 90 by 2 using repeated subtraction also results in 45.

Method 2: Real-Life Example

Let's consider another real-life scenario to illustrate this method. Suppose you have 90 pencils that you want to put into boxes of 2 pencils each. To find out how many boxes you can fill, you can use repeated subtraction.

Starting with 90 pencils, you can subtract 2 pencils repeatedly until you reach zero.

90 pencils - 2 pencils = 88 pencils 88 pencils - 2 pencils = 86 pencils ... 2 pencils - 2 pencils = 0 pencils

Counting the number of subtractions, you can fill 45 boxes with 2 pencils each.

In conclusion, there are two simple ways to calculate 90 divided by 2: basic division and repeated subtraction. Both methods yield the same result: 45. Whether you're sharing cookies among friends or filling boxes with pencils, understanding division can help you solve various real-life problems.
