#6# bones

To solve this issue, take the following two steps: #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 #%# means "out of hundred," put #2.9# over #100#. #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 #10#. #=2.9/100(10/10)# #=29/1000# Determining the Number of Bones Found in the Inner Ear Multiply #206# bones by #29/1000#. #206color(white)(i)"bones"*29/1000# Since #206# and #1000# can be divided by a common factor of #2#, their values are reduced. #=206color(red)(-:2)color(white)(i)"bones"*29/(1000color(red)(-:2))# #=103color(white)(i)"bones"*29/500# Resolve. #=5.974color(white)(i)"bones"# #~~color(green)(|bar(ul(color(white)(a/a)color(black)(6color(white)(i)"bones")color(white)(a/a)|)))#
