Final answer:
Bruce will use 0.10 liters of the blue liquid for his experiment, which is obtained by multiplying 0.25 liters by 0.4.
Step-by-step explanation:
The question asks us to calculate how much of a blue liquid Bruce will use if he has to use 0.4 of the 0.25 liters he was given for an experiment. To answer this, multiply the total amount of blue liquid by the portion Bruce needs to use.
Amount of blue liquid Bruce will use = 0.25 liters × 0.4
To find the amount of blue liquid Bruce will use, simply perform the multiplication:
0.25 × 0.4 = 0.10
Therefore, Bruce will use 0.10 liters of the blue liquid for his experiment.
