Question

How do I turn these decimals into a fraction at its simplest form?

Answer 1

When something repeats, it is often divided by a multipule of 9

when 1 number repeats, it's probably divided by 9,
exmaple, 1/9=0.111111111111

when 2 numbers repeat, then it is probaly divded by 99
example, 14/99=0.14141414

so

21. 0.4444444444=4/9

22. 0.21212121=21/99
