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# . Converting#2.9%# into a fraction.
#2# . Multiplying the fraction form of#2.9%# 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.
