Answer:
Russell needs to weigh out 0.035 grams of powder.
Step-by-step explanation:
Suppose, the weight of the powder in grams [tex]= x[/tex]
Given that, the weight of the powder is 35 milligrams.
The ratio of grams to milligrams is [tex]1:1000[/tex]
According to the given ratio, we will get......
[tex]\frac{x}{35}=\frac{1}{1000}\\ \\ 1000x=35\ \ [by\ cross\ multiplication]\\ \\ x=\frac{35}{1000}\\ \\ x=0.035[/tex]
So, Russell needs to weigh out 0.035 grams of powder.
