Answer:
1/2
Explanation:
If joy completes 1/10 of the painting every day, for her to complete it in five days, we need to add 1/10 with each other five times.
1/10+1/10+1/10+1/10+1/10
Since the denominators are all the same, they stay constant at 10. The numerator we can add since the denominators are the same.
5/10 simplifies to 1/2
