a) 4 : 5

b) 5 : 6

correct answer is: a) 4 : 5

Explanation

The first mixture acid and water ratio is KaTeX parse error: KaTeX doesn't work in quirks mode. or KaTeX parse error: KaTeX doesn't work in quirks mode.
The second mixture acid and water ratio is KaTeX parse error: KaTeX doesn't work in quirks mode. or KaTeX parse error: KaTeX doesn't work in quirks mode.
If we bring the denominator same, we get:
KaTeX parse error: KaTeX doesn't work in quirks mode.
KaTeX parse error: KaTeX doesn't work in quirks mode.
KaTeX parse error: KaTeX doesn't work in quirks mode. In the first mixture water quantity is KaTeX parse error: KaTeX doesn't work in quirks mode.
And, in the second moisture water quantity is KaTeX parse error: KaTeX doesn't work in quirks mode.
KaTeX parse error: KaTeX doesn't work in quirks mode. First mixture KaTeX parse error: KaTeX doesn't work in quirks mode. water quantity is higher.
Ans: 4 : 5 is the first mixture where water quantity is higher.

These precise math questions can also be expressed as:

1. Compare the water levels of two mixtures with ratios of acid to water as 4 : 5 and 5 : 6. Which mixture has a higher water quantity?
2. Identify the mixture with a higher water content between two solutions with acid to water ratios of 4 : 5 and 5 : 6.
3. Compare the ratios of acid to water in two mixtures, given as 4:5 and 5 : 6. Determine which mixture contains a higher quantity of water.
