Convert all to cents and it would be for every 10€ or every dime there was 10€ or two nickles so that means half of 4.20 was nickles

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.
