Do these ratios form a proportion?
$688 per 606 grams
$734 per 619 grams
To determine if these ratios form a proportion, we need to check if the two ratios are equal to each other.
The first ratio is $688 per 606 grams, which can be written as $\frac{688}{606}$.
The second ratio is $734 per 619 grams, which can be written as $\frac{734}{619}$.
To check if these two ratios are equal, we can set up the equation:
$\frac{688}{606} = \frac{734}{619}$
Cross-multiplying, we get:
$688 \cdot 619 = 734 \cdot 606$
Which simplifies to:
$425,272 = 444,804$
Since $425,272$ is not equal to $444,804$, these ratios do not form a proportion.
