An adult has 206 bones. Of those, approximately 2.9% are found in the inner ear. About how many bones in the human body are found in the inner ear?
1 Answer
Explanation:
The two steps to solving this problem are:
1 . Converting2.9% into a fraction.
2 . Multiplying the fraction form of2.9% by the total number of bones in the human body.
Rewriting 2.9% as a Fraction
Since
2.9%
=2.9/100
As there cannot be any decimals in a fraction, you must get rid of the decimal. You do this by multiplying the numerator and denominator by
=2.9/100(10/10)
=29/1000
Determining the Number of Bones Found in the Inner Ear
Multiply
206color(white)(i)"bones"*29/1000
Since
=206color(red)(-:2)color(white)(i)"bones"*29/(1000color(red)(-:2))
=103color(white)(i)"bones"*29/500
Solve.
=5.974color(white)(i)"bones"
~~color(green)(|bar(ul(color(white)(a/a)color(black)(6color(white)(i)"bones")color(white)(a/a)|)))
