O.6 as a mixed number
ella [17]

Answer:

3/5

Step-by-step explanation:

To make 0.6 as a fraction (you can't make it a mixed number because there is no number to the left of the point) place a 1 under it to make it a fraction:

Since you can't have a decimal on a fraction, multiply by 10;

0.6/1 × 10/10 =6/10

Simply your answer (6/10) to get 3/5
