Answer 1

To determine how many tablets of Tylenol to give, we can use the conversion factor of 325 mg per 1 tablet.

Given: 1 tablet = 325 mg

To find: How many tablets are needed for 975 mg?

Solution:

Step 1: Set up the conversion factor:
1 tablet / 325 mg

Step 2: Multiply the given amount (975 mg) by the conversion factor:
975 mg * (1 tablet / 325 mg)

Step 3: Simplify the expression:
975 mg / 325 mg

Step 4: Cancel out the units:
975 / 325

Step 5: Calculate the value:
3

Therefore, you would need to give 3 tablets of Tylenol to reach a total of 975 mg.
