Question

An average person's hair grows at a rate of 19cm per year how fast in inches per month does the average person hair grow in conversion factor round you answer to the nearest tenths

Answer 1

Around 1.6 cm per month

Explanation:

We can set up a proportion to find how much the hair grows per month. It's important to note that there are 12 months in a year, so we can represent a year as 12 months.

`(19)/(12) = (x)/(1)`

We can now cross multiply:

`19\cdot1=19\\\\19/12=1.58\overline{33}`

1.58333... rounds to 1.6.
