Convert the following decimal to a common fraction. reduce to lowest terms 0.2 =

The answer is 1/5 hope this helps

The decimal conversion of 0.2 would be 2/10 since the decimal is rounded to the tenths place. 

When finding the lowest terms of a fraction, you want to find the highest number that can go into both numbers, or greatest common factor (GCF), of both the numerator and the denominator. In this case, the greatest common factor would be 2, since it can go into both 2 and 10 without any remainders. 

2 can go into 2 once, and into 10 five times, making the reduced term 1/5.

I hope I could help! Feel free to reach out if you need any more help with conversions and reductions.
