Round 0.1875 to the nearest hundredth

I get 0.1880, which we normally write as 0.188.

You round 0.1875 by the 7.
I learned, if it's 5 or lower you leave it the way it is. If it's 6 or higher, you round up 1. Therefore; your answer is 0.19

For example, (using your problem)

  0      .     1              8                 7                     5

Zero      Ones      tenths      hundreds       thousands

Q- 2p = p +   4q = -p + 2p + 4q = p + 4p = q - 4 answer
