Answer:
<em>Explanation shown below</em>
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.
<em><u>Multiplying by any number (both numerator & denominator) would make the other ratio equivalent.</u></em>
<em><u>Taking </u></em><em><u>"Square"</u></em><em><u> or </u></em><em><u>"raising to same power" </u></em><em><u> </u></em><em><u>WILL NOT</u></em><em><u> make the new ratio equivalent.</u></em>
Tina "raised 6 to 2nd power to get 36" and "raised 8 to 2nd power to get 64". <em>According to the rules, the new ratio won't be equal</em>.
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.
