Marking brainliest and 50 points it takes chris the same amount of time to do 1/3 of his homework as it does for emily to do 1/2 of hers. at these rates, what fraction of his homework will chris have done by the time emily is finished? a: 1/6 b: 2/3 c: 5/6 d: 3/2

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

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.
