If a dosage of medicine is 2/3 milliliter,how many dosage can be given from a bottle containing 20 milliliter?
20ml / (2/3 ml/dose) = 20(3/2) = 30 doses
Thank you.
To find out how many doses can be given from a bottle containing 20 milliliters when the dosage is 2/3 milliliter, we can use the division method.
First, we divide the total volume of medicine in the bottle (20 milliliters) by the dosage for each dose (2/3 milliliter):
20 milliliters ÷ (2/3) milliliter
To divide a fraction, we can multiply by the reciprocal of the divisor:
20 milliliters × (3/2) milliliter
Now, we can simplify the expression by canceling out the milliliter units:
20 × 3/2
The numerator (20 × 3) gives us 60, and the denominator (2) remains the same:
60/2
Performing the division, we get:
60 ÷ 2 = 30
Therefore, from a bottle containing 20 milliliters, there will be enough medicine to give 30 dosages with each dosage being 2/3 milliliter.
