Best way to convert large fractions to decimals

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?

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%.

Francesco

Hi,

You should approximate it:

50% of 275 = 135

110 is roughly 40%, thus 11 is 4%
