Question 256906: I have a math problem and don't know how to solve it. It has to do with ratios. Just send me what to do and not the answer, so I can do it by myself and say I did my homework. The problem is:
Mario and Lydia were partners on a class project. The ratio of the number of hours that Mario worked on the project to the number of hours Lydia worked was 7 to 8. Together, they worked a total of 30 hours. How many hours did each student work on the project? Explain how you got your answer. Please Help. I would really appriciate it.


Thank You,
I cant solve this math problem

You can put this solution on YOUR website!
Let Lydia's hours be L and Mario's hours be M.
From the ratio, you know,
M%2FL=7%2F8
From the total hours you know,
M%2BL=30
You can solve this since you have two equations with two unknowns.
