Question

One inch equals 2.54 centimeters. How do you Ffnd the length of a newborn, in inches, if it measures 45.7 centimeters?

Answer 1

`45.7` `cm=17.99` inches

Explanation:

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)
