Today, there's a whole web of math issues in singapore in the sixth grade of primary school. Adults are outraged: don't say i can't do it
Let's see what it's called:
Fifty cents translated as follows:
One afternoon, five friends rented three shared bicycles, riding from 5 p. M. To 6. 30 p. M., during which time three bicycles had been riding, assuming that they were riding for the same period of time
And it's supposed to be, "well, how does the math in primary school make it harder than the deposit back?"
And the netizens said, "it's 5:30 p. M., so hot, why are you riding a bike..."
So what's the answer? Don't rush down, take out your little book, give yourself a chance to go back to childhood

Answer one: 54 minutes
The solution is as follows:
Answer two: 18 minutes
The answer is:
Each bicycle is known to have been riding for 90 minutes, with five people riding for the same time, so 90 divided by five to arrive at 18 minutes per person on each vehicle, while three vehicles are naked interference information。
But this standard answer has also been questioned by some math teachers
Because the title doesn't specify any bike, so it's called a ride on a bike, and it's three rotations, 18x3, and it's 54 minutes on a bike
Wow, the language is so sophisticated that it's actually an english test
We can't help but wonder that our maths are taught by english teachers and what is the answer? Or the five friends on the shared bike, can you show us how long you've been riding
All of a sudden, the idea was to make a suggestion to a shared bicycle: the answer to this question could be the security deposit code, the friend who could answer the question could be successful in refunding it, the friend who couldn't answer it...
It doesn't matter if you can't do the sixth grade
This time, it's a girl named cheryl who's trying to help us:
Fifty cents translated as follows:
Albert and bernard met a girl named cheryl. They want to know cheryl's birthday. Cheryl wrote down a list of 10 dates:
15 may-16 may-19 may
17 june-18 june
14 july-16 july
14 august-15 august-17 august
Cheryl whispered to two people, and she told albert how many months her birthday was, and bernard when his birthday was。
Albert said: i don't know how many days cheryl's birthday is, but i know bernard doesn't know。
Bernard said: i didn't know, but now i know。
Albert said, "well, now i know!"
What date is cheryl's birthday
I'm sorry.
I told you, miss cheryl, you can't tell anyone when your birthday is. Is this a new push and pull technique
Fortunately, albert and bernard have a good temper and a good iq. They'd probably choose not to know your birthday or even make friends with you
Friends who can't think, why don't you just look at the solution
I'm miss cheryl's brain circuit
(top down)
Cheryl's birthday has two variables: months and dates, and 10 possible birthdays。
Let's guess what a and b friends think。
Albert states that he knew that bernard also did not know that the stated dates could not be 18 and 19, since both dates had only one corresponding birthday. Albert's certainty that bernard did not know meant that the months he heard were not may and june。
Bernard can speculate from albert's statement that the birthday is in july or august. Since he already knows cheryl's birthday, stating that the date is not 14, otherwise he cannot be sure, we can further narrow the options to 16 july, 15 august and 17 august。
And the key step is, albert says, "oh, now i'm sure cheryl's birthday." according to bernard, albert speculates that he heard one of the 15th, 16th, 17th days, but if he was informed of august, or if he could not determine cheryl's birthday, it could only be july, and july was only one option — 16 july
Friends who have not yet understood do not doubt life, nor blame cheryl for green tea. Because the answer is for the math teacher, and we don't understand it. There's only one thing we want to give to miss c.
So the title of the fifth grade is too difficult, right? What about the first grade title? It's time to meet...
The first grade is simple. It's just a routine. The question is, did you fill it out
Friendship suggests that since it's a first grade topic, you'll have to give up adult thinking
♪ i'm a pure little friend ♪
Correct answer:
Isn't it hard to understand? About you've lost your childish innocence。
The number of children in the first grade can be incalculable, and the first idea to see the subject, of course, is not to add or to multiply it immediately, but to see how many of them are? So, the numbers in the circle are actually in the shape of the fan that shows the circle
Good, good, iq is crushed to the ground。
If your friends look at the three above questions, none of which have been taken up, we suggest that you can put your return to primary school on your own calendar. I've heard that singapore's primary school year is coming up
