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 2/3 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
(x)/(7 3/8) = (23 3/5)/(7 1/2)
(x)/(59/8) = (118/5)/(15/2)
(x) = (59/8)*(236/75)
x = 3481/150
x = 23 13/15 (Head Circumference to nearest 1/15 of inch
x/(7 3/8) = 60/(7.5)
x = (59/8)(60/7.5)
x = 59 cm (Head circumference in centimeters)
