Answer:
Hammad has made his drink stronger in taste than Julie.
Explanation:
We need to compare the ratio of juice to lemonade in each drink.
Julie's drink has a ratio of 42ml juice to 210ml lemonade, which simplifies to 1:5.
Hammad's drink has a ratio of 30ml juice to 170ml lemonade, which simplifies to 3:17.
To compare the strength of their drinks, we need to compare the ratios of juice to lemonade. Since a higher ratio of juice to lemonade indicates a stronger taste, we can see that Hammad's drink has a stronger taste, since his ratio of juice to lemonade is higher than Julie's.
Therefore, Hammad has made his drink stronger in taste than Julie.
