Question 1173395

To convert from centimetres to inches, you can use the fact that a 30-cm ruler is just over 12 inches long. A person is 160 cm tall. what is the person's approximate height, in inches?
<pre>Let approximate height, in inches, be H
Then we get the following PROPORTION: {{{matrix(1,3, 30/160, "=", 12/H)}}}
30H = 12(160) ------ Cross-multiplying
Person's approximate height, or {{{highlight_green(matrix(1,6, H, "=", 12(160)/30, "=", 64, inches))}}}
