Hardly Anyone Remembers How to do Fractions

[Firefighter01]

I own a business where employees need to now how to work out fractions and long multiplication to do their job efficiently.

Don't we have calculators for that already? Maths is just ewww

Lol! I love it when they ask for a calculator for a fractions question and they still can't do it!

I own a business where employees need to now how to work out fractions and long multiplication to do their job efficiently. Here are my questions that I placed in their interview exam to determine if they know basic maths: 
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?

Where these young people just out of school, or older people, who may have forgot from lack of use?  Just curious.  I would think that those just out of school should remember enough to at least attempt it. Someone who hasn't done these things in ten years, I have a little more understanding.

Also, curious what type of job this was?  Perhaps if you our having difficulty, you could test for the necessary aptitude, to do the problems, and those who could relatively quickly be shon how to do the problems.

I find both younger and older people struggle with simple maths. I own a pest control business and the techs need to know how to mix pesticides in the right ratios. I do a lot of training and most pick it up pretty quickly. Unfortunately the really slow ones don't make it past the interview, as it takes too much time to get them competent.
