Problema Solution
Hat size are determined by measuring the circumferences of ones head in either inches or centimeters Use ratio and proportion to complete the following table.
Hat size Head Circumference Head Circumference
(to nearest 1/5 inch) (to nearest centimeter)
7 1/2 23 3/5 60
7 3/8 ______ __________
For the first answer line round to nearest fifth inch as needed. For second answer line round to nearest centimeter as needed
Answer provided by our tutors
Ratio of hat size to head circumference in inches:
23.6/7.5=3.147
In centimeters: 23.6 cm*2.54=59.94 cm
7 /38*3.147=23 1/5 in
23.27 in*2.54=59 cm in diameter
Since the circumference of the head only changed slightly from the first problem you posted, the answers, after being rounded, are about the same.
