Answer and Step-by-step explanation:
To evaluate the ratio 28mg : 7g in its lowest terms, we need to convert the units to the same measurement.
First, let's convert 28mg to grams. Since 1 gram (g) is equal to 1000 milligrams (mg), we divide 28mg by 1000:
28mg ÷ 1000 = 0.028g
Now, we have the ratio as 0.028g : 7g.
To simplify this ratio, we can divide both terms by their greatest common divisor (GCD). In this case, the GCD of 0.028 and 7 is 0.028:
0.028g ÷ 0.028 = 1g
7g ÷ 0.028 = 250g
Therefore, the simplified ratio is 1g : 250g.
This means that for every 1 gram, there are 250 grams in the original ratio.
