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?
14 1/10 hours
3 1/2 hours
46 16/25 hours
1 35/53 hours
To find the difference in hours, we need to subtract the time spent on the art project from the time spent on the science project.
Convert 8 4/5 hours to an improper fraction: 8 4/5 = (8*5 + 4)/5 = 44/5
Convert 5 3/10 hours to an improper fraction: 5 3/10 = (5*10 + 3)/10 = 53/10
Now subtract: 44/5 - 53/10 = (44*2 - 53)/10 = (88 - 53)/10 = 35/10 = 3 5/10 = 3 1/2 hours
So, Victor spent 3 1/2 more hours on his science project.
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.
To begin, let's convert the mixed numbers to improper fractions for easier calculations:
Victor spent 8 4/5 hours on his science project, which can be written as (8 × 5 + 4)/5 = 44/5 hours.
Victor spent 5 3/10 hours on his art project, which can be written as (5 × 10 + 3)/10 = 53/10 hours.
Now, we subtract the time spent on the art project from the time spent on the science project:
44/5 - 53/10
To subtract fractions, we need a common denominator. In this case, the common denominator is 10:
(44/5) × (2/2) - (53/10)
= 88/10 - 53/10
= (88 - 53)/10
= 35/10
Simplifying this fraction, we get:
35/10 = 3 5/10 = 3 1/2
Therefore, Victor spent 3 1/2 more hours on his science project than on his art project.
To find out how many more hours Victor spent on his science project, you need to subtract the time he spent on his art project from the time he spent on his science project.
Victor spent 8 4/5 hours on his science project. To convert the mixed number to an improper fraction, you multiply the whole number (8) by the denominator (5) and add the numerator (4). This gives us (8 * 5 + 4) / 5 = 44/5 hours.
Victor spent 5 3/10 hours on his art project. To convert the mixed number to an improper fraction, you multiply the whole number (5) by the denominator (10) and add the numerator (3). This gives us (5 * 10 + 3) / 10 = 53/10 hours.
Now, to find out how many more hours Victor spent on his science project, you subtract the time spent on the art project from the time spent on the science project:
44/5 - 53/10
To subtract fractions, you need to have a common denominator. In this case, the common denominator is 10. So you multiply the numerator and denominator of the first fraction (44/5) by 2, which gives us (44 * 2) / (5 * 2) = 88/10.
Now, we can subtract: 88/10 - 53/10 = (88 - 53) / 10 = 35/10.
Simplifying the fraction, we get 3 1/2.
Therefore, Victor spent 3 1/2 hours more on his science project.
