Tina says that 6: 8 is equivalent to 36: 64 . what did tina do wrong!

Explanation shown below

Step-by-step explanation:

For 6:8 to be equal to another fraction, Tina needed to MULTIPLY both top and bottom by the same number, NOT RAISE TO A POWER.

Multiplying by any number (both numerator & denominator) would make the other ratio equivalent.

Taking "Square" or "raising to same power" WILL NOT make the new ratio equivalent.

Tina "raised 6 to 2nd power to get 36" and "raised 8 to 2nd power to get 64". According to the rules, the new ratio won't be equal.

Instead of raising to 2nd power, she could multiply by 2 (both numerator and denominator) to get 12:16. This ratio would have been equal to 6:8.
