40% of young people cannot solve this simple example. But you can handle it!
At first glance, it seems that the simplest arithmetic operations with fractions should be performed with a bang by every middle school student. But in fact, light examples are often too tough for even an adult with a higher education.
Recently, a funny experiment was conducted in Japan. Scientists have proposed to solve a simple example of people born in the early 90s. It turned out that among all the respondents only 60% gave the correct answer!
It is noteworthy that 30 years ago exactly the same survey was conducted, and then more than 90% of people successfully coped with this task.
Now our editorial board offers you to test your knowledge. Take a look at the arithmetic example below and solve it. Will you master this task or school knowledge already thoroughly forgotten?
Well, coped with the task? Then check your answer with the correct one!
See the answer below:
4 — 2 ÷ ½ + 1 = 1
If you got a unit in the answer, then you have perfectly mastered the school course of mathematics!
If you thought that the correct answer would be four, then you should repeat the division of fractions. After all, 2 ÷ ½ = 4! But people often forget that when dividing the second fraction, you need to turn it over, and instead of this, by habit, reduce the two, as it should do when multiplying.
Well, if you got another number, it means that you would do well to remember the basics of mathematics. At school you would get a deuce!
Yeah, it just becomes a little uneasy when you realize the pace at which elementary school knowledge is forgotten! Check the level of intelligence of your friends and offer them to solve this simple little puzzle.
