1.1.3.T1 Rounding to n Decimal Places Exercise

Write down each of these numbers rounded to 3 decimal places:

  1. \({@a1@}\)
  2. \({@a2@}\)
  3. \({@a3@}\)
  4. \(−0.5555,\)
  5. \(45.6789\)
  6. \({@a4@}\)

Solution

  1. [[input:ans1]] [[validation:ans1]] [[feedback:prt1]]
  2. [[input:ans2]] [[validation:ans2]] [[feedback:prt2]]
  3. [[input:ans3]] [[validation:ans3]] [[feedback:prt3]]
  4. [[input:ans4]] [[validation:ans4]] [[feedback:prt4]]
  5. [[input:ans5]] [[validation:ans5]] [[feedback:prt5]]
  6. [[input:ans6]] [[validation:ans6]] [[feedback:prt6]]
