Question

How many drahms areequivalent to 300 grains?

Answer 1

hello

to solve this question, we need to know how many grains is in 1 gram

`\begin{gathered} 1\text{grams}=15.43\text{grains} \\ \end{gathered}`

now let 300 grains be equal to x grams

`\begin{gathered} 1\text{grams}=15.43\text{grain} \\ \text{xgrams}=300\text{grains} \\ \text{cross multiply both sides and solve for x} \\ x*15.43=1*300 \\ 15.43x=300 \\ \text{divide both sides by 19.44} \\ (15.43x)/(15.43)=(300)/(15.43) \\ x=(300)/(15.43) \\ x=19.44 \end{gathered}`

300 grains will weigh 19.44g
