# 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.

#=5.974color(white)(i)"bones"#
