My gf supposedly failed the math section, but after going through the questions I found several marked incorrect that, I believe, are actually correct....and one I really have no clue on. If they are correct, then she passed it. Maybe it's been awhile and my math skills (and tagalog skills) have faded. Question 11. View attachment 11110 I have no idea on this one. I read something about the diameter of a square marble tiles.....and I just don't know how that works. Geometry is the Devil's math. Question 21. View attachment 11107 Now if my math is correct the answer is D. 1/6. (1/2)+(1/3)+(1/6)=1 The teacher claims the correct answer is B. 1/3. But reading the question I am under the impression George is trying to make 1 Liter of fertilizer....not 1 and 1/6 liters of the stuff. Question 25. View attachment 11108 The guy saved 1 litro a day by listening to the boss. He washed the car 3 times in a week. The weekly water savings was 3 liters. Maybe a bad translation? Hopefully 2 out of the 3 were correct.
God forbid I got those two questions wrong and then posted it online. That would be pretty d*mn embarrassing.
The way I do it is make all the fractions the same. 1/2 = 3/6, 1/3 = 2/6, 1/6 stays. Then you add the first numbers, leave the second number alone and you come up with 6/6....which divided is 1. Try explaining how this works to your girlfriend over the internet though. Both my parents are teachers (my mom being a math teacher) but teaching is certainly not something that they did a good job of passing on to me. "Look at it!" "I don't know, that's how you do it." "I don't know why it's like that, it just is!" "Yeah, well, I didn't invent math." "Oh, you think I'm wrong? Funny, Google says I'm right." "Then why did you ask me if you already know how to do it?" That's about how my explanation of adding fractions went with her. (Yet, she keeps coming back for more.....I'm assuming because she gets a kick out of getting me going, judging from the laughing.) I also got hit up for an essay question yesterday, "Why is Christmas Very Important". (Yeah, that's exactly how it was worded from the teacher.) First I said, "What if you are Muslim, Jewish or don't believe in God. Wouldn't be very important then, would it?" GF, "I don't know. I just need three paragraphs on why I think it is important." Me, "So you need me to help because....." GF, "I only have two opinions." Me, "Umm, alright. 1. birth of your savior 2. time to spend with family 3. give to the poor." GF, "No, that's not right." Me, "Huh? It's an opinion essay, anything I said was technically correct." GF, "No." Me, lol "What do you mean 'no'? Are you messing with me?" GF, "No" Me, "I gave you my opinions." GF, "But those weren't right." Me, "I really hope you are messing with my head right now. You can figure it out by yourself." (And this is why I will NEVER have kids!)
In regards to the 2nd question , Pretty d*mn hard to pass an exam when the flogging teacher is wrong and wants you to wrong with them .
I recently went through similar here, it was what I deemed to be a simple Sum of addition, multiplication, subtraction and division all rolled into one... So starting from the beginning, I worked out the first equation, gained the answer then moved onto the next, the next then finally the last step, and then was laughed at and told I was WRONG! o.O Now when I went to School, (albeit the transition from Imperial to Metric threw me) Maths was one of my stronger Subjects which I did very well at often resulting in A's and B's for my Exams, but here was a SIMPLE Sum and I was wrong! WTF??? BODMAS o.O NEVER Bloody-well heard of it!! I mean NEVER! What a Crock'o Shyte! Who thought up this Bull-shyte? In the Real World; if one was dealing with a Table full of Fruit there ARE NO BRACKETS, you start from the left (or the right I suppose if you are Chinese hehe) then progress to the end! That is how I WAS taught! No wonder Western Countries are in financial popo! Get a load of this stuff!! :/ [h=2]Order of Operations[/h]Do things in Brackets First.

If you mean the "question 11" and if my gf translated it correctly, then the answer is 7,200: House is 72 sq m. Tiles are 10 cm sq. thus need 100 tiles to tile each sq m of floor. 72 x 100 = 7200 As to the other questions, I agree with the opening post and other posters about the answer. What I don't understand is: What does the teacher say the answers are and why?
You are correct Dave , I have stuffed up , below is section of Wrye's post The teacher claims the correct answer is B. 1/3. But reading the question I am under the impression George is trying to make 1 Liter of fertilizer....not 1 and 1/6 liters of the stuff.
