1/10 of the current U.S. population has diabetes. 2/5 of the people with diabetes has not been diagnosed with the disease. What fraction of the U.S. population has undiagnosed diabetes?
To find the fraction of the U.S. population with undiagnosed diabetes, we need to multiply the fractions representing the proportion of the population with diabetes and the proportion of people with diabetes who are undiagnosed.
1/10 * 2/5 = 2/50 = 1/25
Therefore, 1/25 of the U.S. population has undiagnosed diabetes.
