Approximately one-seventh of the people in the United States are left-handed. The population of the United States is about 300 million. Write and solve an equation to estimate howmany people in the United States are left handed.
(1/7)(300) = 300/7 = 42.85 = about 43 million

You're welcome.
To estimate the number of left-handed people in the United States, we can set up a proportion based on the given information.
Let's say x represents the estimated number of left-handed people in the United States.
The proportion can be set up as:
(left-handed people in the United States) / (total population of the United States) = (1/7)
which can be written as:
x / 300 million = 1 / 7
To solve for x, we can cross-multiply and then divide:
x = (1/7) * 300 million
x = 42.9 million (rounded to the nearest tenth)
Therefore, an estimated 42.9 million people in the United States are left-handed.
