200 is the whole and 120 is the part.
You want to know what percent the part is of the whole.
The whole is always 100%.
You know this:
whole is 100% and is 200
part is x% and is 120
Set up a proportion:
\(\dfrac{100}{x} = \dfrac{200}{120} \)
Now solve for x by cross multiplying:
\(200x = 100 \times 200\)
\(200x = 12,000\)
\(x = \dfrac{12,000}{200} \)
x = 60
Answer: 60%
