# Simplify fractions

You don't have to use a translator - feel comfortable to post in your own language. Some translators are not accurate, which complicate things. We use the Yandex Translate in our community, which might be more accurate.

Also, saying that you don't have time is not an excuse for not learning App Inventor. Without learning the basics of App Inventor, how are you going to build a successful app?

Learning things all take time. Instead of thinking the product, think about how to make the product.

To turn a decimal number into a numerator and denominator,

• split the number at '.'
• if the resulting list has only 1 item,
• then the numerator is item 1 and the denominator is 1.
• else
• set local power = 10 ^ (text length of item 2)
• numerator = original number * power
• denominator = power

Example with 3.14 as original number
Split at '.' to get list [3,14]
Length ('14') = 2
power = 10 ^ 2 = 100
numerator = 3.14 * 100 = 314
denominator = 100

Yes you're right, but this is what I get.

Usually you might want to get a whole number as a decimal result, but that's ok.

Also, the fraction can be simplified. In the screenshot below, the top result is with built-in blocks, the next one is the extension.

That's an interesting counterexample (math block 0.124354)

I think it failed in my code because of the inexact nature of AI2 floating point numbers.

Thanks, that was fun.
