Answer:
B: 2/3
Step-by-step explanation:
homework = rate* time
Divide each side by rate
homework /rate = time
Chris:
1/3 homework/ rate = time
Emily :
1/2 homework / rate = time
The times are equal
Emily Chris
1/2 homework/ rate = 1/3 homework/ rate
Multiply by 2
1 homework / rate = 2/3 homework/ rate
When Emily is done, Chris will be 2/3 done
Answer:
B. 2/3
Step-by-step explanation:
Note that for the completion of the homework, it would have to be:
For Chris: 3/3 or 1
For Emily: 2/2 or 1
respectively.
For Emily to complete her homework, she must have 2/2. Multiply 2/1 to her fraction:
(1/2)(2/1) = 2/2 = 1
Multiply 2/1 to Chris's amount too (as the same number of time passes).
(1/3)(2/1) = 2/3
At the rate that Emily finishes her homework, Chris would be B) 2/3 done with his.
