Answer 1

Answer:

The answer is "3.81041978"

Explanation:

$\to 1 \ OZ= 28.349523125 \ grams$

              $=28.349523125\times {1000} \ miligrams\\\\= 28349. 5231 \ miligrams$

In 1860 $= 28349.5231 \ miligrams$

$\to In \ \ 1 = \frac{28349.5231}{1860} \ \ miligrams$

             $= 15.2416791 \ miligrams$

$\ In \ 1 \ quarter = \ \ 0.25$

$\to \ \ 0.25 = 15.2416791 \times 0.25 \ miligrams$

              $= 3.81041978$
