E.g. I got stuck on how to do 11/275 during a case
What is the best trick for something like this and many others
Are there any recourses to practice large fractions?

Hi,
here you can find a detailed approach to solve it in a quick approximated way and in an accurate way: https://www.youtube.com/watch?v=do_IbHId2Os
I recommend you to take a look at the channel, I really appreciate their video on fast math.

Hi,
If you haven't checked, you can use the mental math tool on preplounge:

The best way to do is to break into simpler numbers wherever (numerator or denominator) large number exists.
E.g. 11/275
Step 1: 275 is the number you want to break --> 25 * 11 = 275
Step 2. Put it in fraction. Now, your equation becomes --> 11/ (25*11)
Step 3. Solve the new equation into simpler form --> 1 / 25
Step 4. Convert 1 / 25 into fraction (1 / 25) * (100 / 100) = 0.04, only if you cant do from Step 3 directly
Hi Anonymous,
assuming you can approximate numbers, in this case you can find what is a relatively small percentage (eg 1%) and see how the number you have to calculate compares to that.
In this case, 1% of 275 is 2.75, which means 2% is 5.5. At this stage, you would probably notice that 11 is therefore exactly 4%.

Hi,
You should approximate it:
50% of 275 = 135
110 is roughly 40%, thus 11 is 4%
