#45.7# #cm=17.99# inches

As #2.54# #cm# is equal to #1# inch

#:.1# #cm# is equal to #1/2.54=100/254# inch.

and #45.7# #cm# is equal to #100/254xx45.7#

= #100/254xx457/10#

= #(10cancel100)/254xx457/(1cancel10)#

= #4570/254~=17.99# inches (using calculator)

To find the length of a newborn in inches if it measures 45.7 centimeters, you can use the conversion factor:

[ 1 \text{ inch} = 2.54 \text{ centimeters} ]

So, to convert 45.7 centimeters to inches, you divide by the conversion factor:

[ \text{Length in inches} = \frac{45.7 \text{ centimeters}}{2.54 \text{ centimeters/inch}} ]

[ \text{Length in inches} = \frac{45.7}{2.54} ]

[ \text{Length in inches} \approx 18 \text{ inches} ]
