explain the error Tina says that 6:8 is equivalent to 36:64 what did tina do wrong

Answer 1

Tina said that 6:8 is equal to 36:64.
It's wrong. It should be 48:64. Because just like a fraction, whatever you multiply in the bottom, you do to the top.

Answer 2

When Tina multiplied, 6:8 to become 36:64 she didn't do the same to the same sides. In order to make it right, you would be 36:48 or 48:64
