Final answer:
The second solution with 6 parts sugar and 7 parts water has a higher concentration of sugar compared to the first solution of 3 parts sugar to 4 parts water.
Step-by-step explanation:
When comparing which solution has more sugar, it's important to look at the ratio of sugar to the total parts (sugar + water).
The first solution has 3 parts sugar and 4 parts water, making a total of 7 parts. To find the concentration of sugar, we calculate 3 divided by 7, which gives us approximately 0.429.
The second solution has 6 parts sugar and 7 parts water, for a total of 13 parts. Here, we calculate 6 divided by 13, which is roughly 0.462.
Since 0.462 is greater than 0.429, the second solution with 6 parts sugar and 7 parts water has a higher concentration of sugar.
