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

Thanks

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.
