Hey, it’s your friend Brad again. And today is your percentage practice day on eurosaiop.org!
I recently visited my cousin’s school and met his teachers in a PTM. It was cool, except that his mathematics teacher, Mr. Hubbert, asked me to make him practice ‘Percentage’ more.
He also mentioned that lots of adults are now dependent on calculators and mobile phones too. With AI models and quick answers, we are forgetting our mathematical skills.
And therefore, I decided to not only teach him some percentages, but refresh my own calculations too.
I picked up these 50 questions and went on to solve them. Now, I have written solution here, but I want you guys to solve these 50 questions first before you look at the solution. Okay?
Solve these 50 questions to polish your percentage calculation
Please note that I have only included small numbers up to 1000 here. This makes it easier for us to practice these percentage questions in our mind without a pen and paper.
In any condition, you have to do these:
- Do not get bored and solve all of these.
- Do not use a calculator.
- Do not use mobile phone to calculate.
- Do not eat pizza while doing this. This one’s optional though!
Ready?
Get. Set. Goooooooo!
Start solving.
1. 40 is what percent of 50?
Think of it this way: If 50 is like a whole pizza and you have 40 slices, how much of the pizza do you have?
👉 Divide 40 by 50 (40 ÷ 50 = 0.8).

So, 40 is 80% of 50.
