SUMMARY

The discussion focuses on converting the repeating decimal 0.1333... into a fraction. Participants explain that 0.1333... can be expressed as the sum of 0.1 and 0.0333..., where 0.1 equals 1/10 and 0.0333... equals 1/30. The final fraction is derived by adding these two fractions, resulting in 1/10 + 1/30, which simplifies to 4/30 or 2/15. This method of conversion is based on established mathematical principles for handling repeating decimals.

is it 1/30?
Spot on. Now, RE one of my previous posts
Hootenanny said:
0.1\dot{3} = 0.1 + 0.0\dot{3}
So, we now know that 0.1 = 1/20 and 0.03333 = 1/30, thus;

0.1\dot{3} = 0.1 + 0.0\dot{3} = \frac{1}{10} + \frac{1}{30} = ?

Can you go from here?

No, you need to find a common factor between 4 and 30.

You need to find a number that divides perfectly into both 4 and 30. For example, a common factor of 6 and 4 is two. Since when you divide 6 by 2 you obtain 3 and when you divide 4 by 2 you obtain 2.
