1/10 of the current US population has diabetes 2/5 of the people with diabetes have not been diagnosed with a disease what fraction of the US population has undiagnosed diabetes to write the answer in simplest form

To find the fraction of the US population with undiagnosed diabetes, we need to multiply the fraction of people with diabetes by the fraction of people with undiagnosed diabetes.

Fraction of people with diabetes = 1/10
Fraction of people with undiagnosed diabetes = 2/5

Fraction of US population with undiagnosed diabetes = (1/10) * (2/5)
= 1/25

Therefore, the fraction of the US population with undiagnosed diabetes in simplest form is 1/25.
