Maybe they didn't forget them, but they use their lack of memory as an excuse where they didn't learn them (or were not taught) correctly in the first place?

1. 1/4 + 1/3 =
2. 1/4 x 1/3 =
3. 132 x 64 =

Only about 3 applicants over dozens that have sat the exam have answered all questions correctly. Most of them got the last one right, but they used their mobile phones.  I originally thought that the questions were too easy, but apparently they are now redundant? I don't know why teachers today don't teach fractions so that their students are competent in their usage, or is it a case that they aren't considered important enough to warrant any special attention?

Operations with fractions were always taught between 2 and 3 years before students came to me.  Part of the failure of the american education system traditionally has been that we teach a shit load of things every year and then go on reteaching them since we never do any of it in enough depth to stick.  So I almost always had to work in some review too.  With the common core that was implemented just before I retired there is a chance this cycle will finally be broken. But then there are so many other things wrong with the education system as a whole that I wouldn't bet on it.  The only think I am positive about is that if we continually jump between one reform system and another forever students are screwed.
I'm no expert or teacher, I'm just a layperson. I remember an older neighbouring kid came to see me for help when I was about 17 and still living at home. He was trying to get into the navy and failed their entrance exam, mainly on his ignorance on how to work out simple fractions, decimals and percentages. He said he never understood them at school and always got terrible grades. We sat down and I explained what they are and how to solve them. We worked on them separately over a week using lots of examples until he mastered them all by himself. It was like lights going on in his head.

It was obvious that he got lost in the system. I felt something similar when I was trying to get a project completed when I was working in a commercial fire safety branch of the fire brigade. I got enrolled in a course called "Microsoft Project" and was placed in a class of about 30 people, most of whom were building estimators or were high end tradespeople. Whenever the teacher said "got that?" everyone except me said, "yeah, yeah" and he skipped to the next section. I kept asking questions, but in the end stopped as it was getting embarrassing. I ended up getting a certificate of attendance, but I didn't deserve anything. The teacher told me later that I would have to take some other introductory courses, but I never followed through.
