you need to know your conversion factors.

How many ml are in a tsp?

How many mg are in a grain?

question number 1 is worded incorrectly, the order should be for mg.

The only way to get good at this is to memorize the conversions.

Write them out over and over again until you get it stuck in your head.

1. if you meant to type mg then...

(d)order: 25mg

(h)supply: 20mg/tsp

d/h x q= x

25mg/20mg x 1tsp = x

1.25 x 1tsp = x

1.25 tsp = x

1 and 1/4 tsp = x

give: 1 and 1/4 tsp

2.

gr 1=60mg

gr 3/4=45mg

(d)order: gr 3/4 (45mg)

(h)supply: 50mg tab(q)

d/h x q= x

45mg/50mg x 1tab = x

0.9 x 1tab = x

0.9 tab(s) = x

0.9 is almost 1...

1 tab = x

give: 1 tab

that's what i came up with, someone can double check.
