Math puzzles have a way of capturing our attention, especially when they appear deceptively simple at first glance. You’ve likely encountered a problem that looks straightforward but leaves you scratching your head once you start working through it. One such problem is the following:
Can you solve this?
1/5 ÷ 1/5 ÷ 1/5 ÷ 1/5
At first glance, it might look easy—a string of divisions between fractions. But as with many math puzzles, the devil is in the details. It’s not about complex math; rather, the challenge comes from ensuring you follow the right steps. Let’s dive into the solution and see why problems like these often trip people up.
Common Mistakes People Make with Fraction Division
Before we get into solving this, let’s highlight some of the frequent mistakes people make when solving similar puzzles. Understanding these errors will help ensure you don’t fall into the same traps.
1. Ignoring the Order of Operations
Order of operations is crucial in math, and that includes division problems. When faced with multiple operations, especially division, it’s essential to solve them in the correct order from left to right. Skipping or mishandling these steps can quickly lead to the wrong answer.
2. Misinterpreting Fraction Division
Dividing fractions is one of those areas where small errors can lead to large mistakes. The rule for dividing fractions is simple: multiply by the reciprocal. However, many people either forget this step or apply it inconsistently.
3. Assuming All Terms Cancel Out
Another common mistake is assuming that, because all the fractions are the same, they will cancel each other out and leave a simple answer like 1. While that might seem logical at a glance, it overlooks the actual math involved in each division step.
Now that we’ve covered the potential pitfalls, let’s go through the solution step by step.
Step-by-Step Breakdown of the Problem
The problem we are solving is:
1/5 ÷ 1/5 ÷ 1/5 ÷ 1/5
Let’s take it one division at a time.
First Division: 1/5 ÷ 1/5
To divide fractions, you multiply by the reciprocal of the second fraction. In this case, dividing 1/5 by 1/5 means multiplying by 5:
1/5 ÷ 1/5 = 1/5 × 5 = 1
So, after the first division, we are left with 1.
Second Division: 1 ÷ 1/5
Now, we move on to the second division, which is 1 divided by 1/5. Again, we multiply by the reciprocal of 1/5, which is 5:
1 ÷ 1/5 = 1 × 5 = 5
After the second division, we have 5.
Third Division: 5 ÷ 1/5
Finally, we divide 5 by 1/5. Following the same rule, we multiply by the reciprocal of 1/5:
5 ÷ 1/5 = 5 × 5 = 25
And there you have it! The correct answer is 25.
