A 200 ml cup is 3/4 full. A 120 ml glass is 1/4 full. What is the total fluid amount?
180 ml is the total fluid amount when combining the contents of the cup and the glass.
To find the total fluid amount, we need to calculate the fluid in the cup and the glass separately and then add them together. The cup holds 200 ml and is 3/4 full, which gives us 150 ml. The glass holds 120 ml and is 1/4 full, resulting in 30 ml. Adding these amounts together yields a total of 180 ml.
This option incorrectly sums the fluid amounts. If one were to mistakenly calculate the fluid in the cup or glass, they might arrive at 140 ml by incorrectly assuming lower quantities. However, the proper calculations yield a higher total.
This is the correct total fluid amount. The cup, being 3/4 full, contains 150 ml (200 ml * 3/4), and the glass, being 1/4 full, contains 30 ml (120 ml * 1/4). The correct addition of these amounts (150 ml + 30 ml) results in 180 ml.
This choice suggests an incorrect total that may arise from adding the full capacities of both the cup and the glass rather than their current fluid levels. If one adds 200 ml (full cup) and 120 ml (full glass), it totals 320 ml, which is not the fluid amount in either vessel.
This option represents the sum of the full capacities of both the cup and glass combined (200 ml + 120 ml), which does not reflect the actual fluid levels present in either container. The correct total is derived from the actual amounts of liquid they contain, not their maximum capacities.
In summary, the total fluid amount from a 200 ml cup that is 3/4 full and a 120 ml glass that is 1/4 full is 180 ml. The calculations demonstrate how to derive the volume of liquid based on the current fill levels rather than their full capacities, emphasizing the importance of accurate measurements in determining totals.
