determine the ratio for the following drugs and simplify to the lowest term possible.

1. 750 mg tablet of clarithromyan
2. 125 mg of amoxicillin in 5 ml
3. 300 mg raniticline in 2 ml

To determine the ratio for the given drugs, we need to express the quantities in a common unit. Let's convert all the quantities to milligrams (mg), which is a standard unit in medicine.

1. 750 mg tablet of clarithromycin:
The ratio here is 750 mg per 1 tablet. Since there is only one tablet, the ratio remains the same: 750 mg : 1 tablet.

2. 125 mg of amoxicillin in 5 ml:
To calculate the ratio, we need to know the milligrams per milliliter (mg/ml) concentration of amoxicillin. If we assume it to be a 1:1 ratio (which is often the case), then the ratio would be 125 mg : 5 ml. However, it's important to note that the concentration might vary depending on the specific formulation.

3. 300 mg ranitidine in 2 ml:
The ratio here is 300 mg : 2 ml.

To simplify the ratios to the lowest term possible, we need to find the greatest common divisor (GCD) of the quantities in the ratio.

1. 750 mg : 1 tablet:
The GCD of 750 and 1 is 1. Therefore, the simplified ratio is 750 mg : 1 tablet.

2. 125 mg : 5 ml:
The GCD of 125 and 5 is 5. By dividing both quantities by 5, we get the simplified ratio: 25 mg : 1 ml.

3. 300 mg : 2 ml:
The GCD of 300 and 2 is 2. By dividing both quantities by 2, we get the simplified ratio: 150 mg : 1 ml.
