i'm going through the numeracy practise test online and part of my problem is i'm getting the answers wrong because i dont know how to solve the actual question so i have no clue on how to correct it. I've looked online for solutions but cant find anything, so if anybody could explain to me how to actually solve these questions without just giving me the answer that would be really appreciated. it doesn't matter how many times i go over the test, i will remember the correct answer but will have no idea how to actually work it out when it comes to the real test when the answer if different.
