Answer:
6 grams of sugar in 3/4 liter.
Step-by-step explanation:
Recall that two 1/4 portions is equal to 1/2. So if 1/2 liter has 4 grams, 1/4 liter will have 2 grams of sugar.
Every 1/4 liter will have 2 grams of sugar.
Therefore, 3/4 liter will have 3 times as much sugar as 1/4 liter. The amount of sugar in 3/4 liter will be 3 times 2 grams or 6 grams of sugar in 3/4 liter
