Step-by-step explanation:
We need to convert 25 cg : 4g in lowest terms.
We know that, 1 gram = 100 centigram
1 cg = (1/100) gram
25 cg = [tex]\dfrac{25}{100}[/tex] grams
To write 25 cg : 4g in lowest terms, the step to be done are as follows :
[tex]\dfrac{25\ cg}{4\ g}=\dfrac{\dfrac{25}{100}}{4}\\\\=\dfrac{\dfrac{25}{25\times 4}}{4}\\\\=\dfrac{1}{16}[/tex]
It means that the lowest term for 25 cg : 4g is [tex]\dfrac{1}{16}[/tex]
