Which correctly compares their ratios of blue to yellow paint?
$\frac{3}{2} > \frac{5}{2}$
$\frac{5}{3} > \frac{2}{2}$
To determine which ratio comparison is correct, we analyze two given inequalities: \(\frac{3}{2} > \frac{5}{2}\) and \(\frac{5}{3} > \frac{2}{2}\). A ratio \(\frac{a}{b}\) represents a comparison between two quantities, and we determine the validity of the inequalities by evaluating the decimal or fractional values of each side.
First, we examine the inequality \(\frac{3}{2} > \frac{5}{2}\).
Converting the fractions to decimals, we have:
\[ \frac{3}{2} = 1.5 \]
\[ \frac{5}{2} = 2.5 \]
Since \(1.5\) is not greater than \(2.5\), the inequality \(\frac{3}{2} > \frac{5}{2}\) is mathematically incorrect.
Next, we examine the inequality \(\frac{5}{3} > \frac{2}{2}\).
Converting the fractions to decimals or common denominators:
\[ \frac{5}{3} \approx 1.667 \]
\[ \frac{2}{2} = 1 \]
Since \(1.667\) is clearly greater than \(1\), the inequality \(\frac{5}{3} > \frac{2}{2}\) is mathematically correct.
By comparing the two evaluations, we find that the first statement is false, while the second statement, \(\frac{5}{3} > \frac{2}{2}\), is true. Thus, the correct ratio comparison is \(\boxed{\frac{5}{3} > \frac{2}{2}}\).
In painting or cooking, ratios are essential for maintaining consistency. For example, if you are mixing a shade of green paint, you might need a ratio of 5 parts blue to 3 parts yellow. Knowing that this ratio is greater than 1, you can conclude that there is more blue paint than yellow, which is important for achieving the desired color density in your project. Efficiently comparing these ratios ensures you get the perfect mix every time!
