Answer:
5 drahms are equal to 300 grains.
Explanation:
First, I figured out that 1 drahm is equal to 3 scruples, which are equal to 60 grains.
So, 60 grains = 1 drahm.
Then, I multiplied the number of grains for one drahm by x, the number of drahms that are equal to 300 grains.
This translates to the equation 60 x X = 300.
60 x 5 = 300 grains, which means 5 drahms equal to 300 grains.
Hope this helps.
