Final answer:
Connie finished 7/10 of her project the whole day.
Step-by-step explanation:
To solve this problem, we need to find the part of the project that Connie finished in the morning, the remaining part of the project, and the part she finished in the afternoon.
Connie finished 3/5 of her project in the morning, which can be represented as 3/5 * 1 = 3/5.
The remaining part of the project can be found by subtracting the part Connie finished in the morning from the whole project. So, the remaining part is 1 - 3/5 = 2/5.
Connie then finished 1/4 of the remaining part in the afternoon, which can be represented as 1/4 * 2/5 = 2/20 = 1/10.
To find the part of the project that she finished the whole day, we need to add the part she finished in the morning (3/5) to the part she finished in the afternoon (1/10). So, the part she finished the whole day is 3/5 + 1/10 = 6/10 + 1/10 = 7/10.
