Answer:
7.5 fluid ounces
Step-by-step explanation:
Fraction of fluid ounce poured into each test tube
Number of test tubes filled = 10
The number of fluid ounces poured is the product of the amount poured into each test tube and the number of test tubes filled
Therefore, total amount poured :
(3/4 fluid ounces) * 10
0.75 * 10
= 7.5 fluid ounces
