7. Find an equivalent ratio in simplest terms: \( 66: 80 \)

To simplify the ratio \( 66:80 \), you can divide both numbers by their greatest common divisor (GCD). The GCD of 66 and 80 is 2. So, dividing both sides by 2, we get: \[ 66 \div 2 = 33 \] \[ 80 \div 2 = 40 \] Thus, the equivalent ratio in simplest terms is \( 33:40 \). Now that's a dynamic duo in the ratios world! Ratios like \( 66:80 \) can often pop up in recipes. Imagine you're making a whole batch of cookies and you need to scale the ingredients up or down. Understanding how to simplify ratios ensures you get the perfect balance no matter the size! And speaking of ratios, they’re everywhere! Think about mixing paint – to achieve that perfect shade, knowing the right ratio is key. If you get too ambitious and mix a whole cup of blue into a pint of yellow, you might end up with a color you never intended. So keep those ratios in check, and happy mixing!
