Then, to find four fifths of a number, we first find one fifth of that number and then multiply this by four.

I am doing well with discounts and percentages of numbers. I need to work on discounting word problems.
I learnt how to use a calculator to help me calculate the answers for finding percentages and discounts of a price/number. I need to focus on remembering that I have to minus the percentage from the whole number.

Overall on my test, I think I did pretty good as I expected I may have gotten a lower score. I still need a little work on some thing’s like the deposit, I know what it mean’s I just forgot at the time, also I think I may have read a few questions incorrectly, but I still think I did the best I could.
Thanks, abs
What I did well?
I calculated the percentage of a whole number easily
What I need to improve on?
Reading the questions properly and proof checking my work.
I mainly need to focus on, multi – step problems. Also checking my answer when finding the discounts. I know how to find all percentages of money. I know how to discount the percentage of the money but don’t know how to find the final answer.
I will make sure that I read the question more carefully, I am proud of my results considering that I just have to read the question more carefully.
I have done my discounts well, but need to get my deposit right. I need to also learn how to minus the discount, percentage and deposit.

Thank you for marking my work. Overall, I think I did a pretty good job as I thought that I might have gotten a little lower, I still need work on the deposit part as I just forgot what it mean’s in that moment in time,
Thank you, abs
