Question

A certain drink contains 8 parts of subtance A and 4 parts of substance B. If 752 mL of substance A is used, how many milliliters of substance B should be used?

Answer 1

To find out how many milliliters of substance B should be used, we need to determine the ratio of substance A to substance B. The ratio is 8 parts of substance A to 4 parts of substance B, which can be simplified to 2 parts of substance A to 1 part of substance B. Therefore, 376 milliliters of substance B should be used.

Step-by-step explanation:

To find out how many milliliters of substance B should be used, we need to determine the ratio of substance A to substance B. In this case, the ratio is 8 parts of substance A to 4 parts of substance B, which can be simplified to 2 parts of substance A to 1 part of substance B. Since 752 mL of substance A is used, we can set up a proportion to find the unknown amount of substance B:

2 parts A / 1 part B = 752 mL A / x mL B

Cross-multiplying and solving for x, we get:

2x = 752 mL * 1 part B / 2 parts A

x = 752 mL * 1 / 2 = 376 mL

Therefore, 376 milliliters of substance B should be used.
