Question 1

A patient has a bottle of liquid medicine that contains 60 doses of medicine. How many days will the bottle last if the patient takes 4 doses a day?

Answer 1

15 days
Know Want to Know
4 doses : 1 day :: 60 doses : x days
$\begin{array}{l}\frac{4 x}{4}=\frac{60}{4} \\x=15 \text { days }\end{array}$
Proof: 4 * 15 = 60
1 * 60 = 60

Question 2

Solve for x , and prove your answer: 2 : 5 :: 10 : x

Answer 2

x = 25
Know Want to Know
2 : 5 :: 10 : x
Proof: 2 * 25 = 50
5 * 10 = 50

Question 3

There are 50 syringes in each package. The hospital uses 50 packages a week. How many syringes does the hospital use in a week?

Answer 3

x = 50 * 50 x = 2500 syringes
Proof: 50 *50 = 2500
1 *2500 = 2500
