60 split by 0.4 = 150

The 0.4 mg tablet computer represents 1/150 that 60 (1 grain)

The 0.4 mg tablet represents 1/150 gr

do you agree?

you are ordered to give nitroglycerine gr 1/150. The pharmacy has actually supplied 0.4mg/tablet. How numerous tabs need to you give?

first of all, convert the dose wanted of 1/150 grains into milligrams. This is a proportion (fraction) equivalency problem, thus:

by using a conversion element to transform the grains to milligrams. Watch what i perform with the left next of his equation:
so, girlfriend now recognize that 1/150 serial is the very same as 0.4 mg. Your trouble says that the pharmacy has actually supplied you through 0.4 mg tablets. Because you now recognize that the dose ordered, in it"s convert mg kind is 0.4 mg, girlfriend will give

start by figuring how many grains in every tablet:

you"re offered that each tablet has 0.4 mg and you recognize that 1 grain is 60 mg. Therefore:

0.4 mg/tab x 1 gr/60 mg = 0.4/60 gr/tab

now, clear the nasty decimal native the numerator (divide the numerator and the denominator through 0.4 each) :

0.4/60 gr/tab = (0.4/0.4) / (60/0.4) gr/tab = (1)/(60/0.4) gr/tab

(1)/(60/0.4) gr/tab = (1)/(150) gr/tab

recognize in that:

anything split by itself = 1if you division the numerator and also the denominator by the same value (e.g. 0.4 in this case), you"re not changing the value since you"re basically multiplying by 1.

You are watching:
Convert 150 grains to milligrams

recognize in that:

the units are consistent: mg/tab x gr/mg = gr/tab because the mg terms cancel.
