Ashley and Nick worked on a math project together. Ashley finished 1/6 of the project and Nick finished 2/8 of the project. How much more of the project is left?
A: 3/4 B: 7/12 C: 5/6 D: 7/24
My answer: I think it's 7/12 but i'm not sure.
1/6 = 2/12
2/8 = 1/4 = 3/12
2/12 + 3/12 = 5/12
12/12 - 5/12 = 7/12
You're right.
Thank you.
You're welcome.

To find out how much more of the project is left, we need to calculate the sum of the fractions completed by Ashley and Nick and subtract it from 1 (representing the entire project being completed).
Ashley finished 1/6 of the project, while Nick finished 2/8. Since 2/8 can be simplified to 1/4 (by dividing the numerator and denominator by 2), we have:
Ashley's fraction: 1/6
Nick's fraction: 1/4
To add these fractions, we need a common denominator. The least common multiple of 6 and 4 is 12. Multiplying the numerators by appropriate factors to get a common denominator, we get:
Ashley's fraction: (1/6) * (2/2) = 2/12
Nick's fraction: (1/4) * (3/3) = 3/12
Now, we can add these fractions together:
2/12 + 3/12 = 5/12
So, Ashley and Nick completed a total of 5/12 of the project.
To find out how much more is left, we subtract this fraction from 1 (the whole project):
1 - 5/12 = 12/12 - 5/12 = 7/12
Therefore, the correct answer is B: 7/12.
