Hey Kat! :)
Glad to see you on Brainly.
Look below and watch how we solve this problem.
Ask any questions if you need it! I'll respond when you need it!
This is a bit of a hard, one. So please ask questions.

Please use the rule a/b x c/d = ac/bd while solving.
After using that equation, it should look like this:
2 x -5 x -3 / 7 x -8
Simplify 2 x -5 to -10.
Now, it should look like -10 x -3 / 7 x -8
30/7 x -8
30/-56
- 30/56 (the negative is front of the WHOLE equation.)
-15/28 is our final answer.
Would it be 2:1? I really don't know, I haven't learned that yet, sorry
Answer:
13/24
Step-by-step explanation:
Find the LCD of 8 and 3, which is 24.
Now, multiply both numerators so that the following fractions would be equal:
7/8 = x/24
1/3 = y/24
Our result is that
7/8=21/24
1/3 = 8/24
21/24 - 8/24 = 13/24
