Answer:
30 gram doses
Step-by-step explanation:
First, turn the fractions into decimals.
1/4 gram to .25 gram
7 1/2 gram to 7.5 gram
Then, divide 7.5 total grams by the .25 grams for each dose.
7.5/.25 = 30
Therefore, you can obtain 30 1/4 gram doses from a 7 1/2 gram vial of medication.
Given:
Weight of the vial = [tex]7\frac{1}{2}[/tex] grams
Weight of one dose = [tex]\frac{1}{4}[/tex] gram
To Find:
Number of doses in one vial.
Solution:
Let the number of doses in a vial = n
Therefore, weight of 'n' doses = [tex]n\times \frac{1}{4}[/tex]
= [tex]\frac{n}{4}[/tex] grams
Since, the weight of the n doses is equal to the weight of one vial,
[tex]\frac{n}{4}=7\frac{1}{2}[/tex]
[tex]\frac{n}{4}=\frac{15}{2}[/tex]
[tex]n=\frac{15\times 4}{2}[/tex]
[tex]n=30[/tex] doses
Therefore, 30 doses can be obtained from one vial of medication.
