To find out how many more hours Victor spent on his science project, we need to subtract the time he spent on his art project from the time he spent on his science project.
Converting the mixed numbers to improper fractions:
8 4/5 = 44/5 hours
5 3/10 = 53/10 hours
Now we can subtract:
44/5 - 53/10
To subtract fractions, we need to have a common denominator. The least common multiple of 5 and 10 is 10, so we need to convert the fractions to have a denominator of 10.
44/5 = (44/5) * (2/2) = 88/10
53/10
Now we can subtract:
88/10 - 53/10 = (88-53)/10 = 35/10
Now let's simplify the fraction:
35/10 = (35/5) * (2/2) = 7/2
So, Victor spent an additional 7/2 hours on his science project, which is equal to 3 1/2 hours.
Therefore, the correct answer is:
3 1/2
hours.
It took Victor 8 4/5
hours to complete his science project and 5 3/10
hours to finish his art project. How many more hours did Victor spend on his science project?(1 point)
