About 8 to 10 U.S Households have TV remote controls. There were 129,200,000 U.S. Households in 1998. How many households have TV remote controls? SET UP A PROPORTION

Answer 1

This is the proportion
\[\frac{ 10 }{ 129,200,000 }=\frac{ 8 }{ ? }\]
This is how to solve it. One of the most popular ways is by cross multiplying.
So first 8 x 129,200,000
8 x 129,200,000 = 1,033,600,000

Next divide your answer by 10
1,033,600,000/10 = 103,360,000

So the answer is 103,360,000 households had remotes.

Answer 2

SO IT WOULD BE 8/103,360,000 OR JUST 103,360,000

Answer 3

depending how they want it written, it would either be 8/1,033,600,000 or just 103,360,000.
