Answer the following questions.
serg [7]
39 is <span>312% </span>of 12.5

To find this you just divide 12.5 into 39 which gives you 3.12. To change that to a percentage you multiply by 100 which gives you 312%

7.5 is <span>102% </span>of 7.38

To find this you just divide 7.38 into 7.5 which gives you 1.0162, which I rounded to 1.02. To change that to a percentage you multiply by 100 which gives you 102%

I hope this helped! :)

----------------------------

  • The mid-afternoon temperature in January is of -12.6ºC.
  • In July, it is of 26.1ºC.
  • The difference of the temperatures is given by:

26.1 - (-12.6) = 26.1 + 12.6 = 38.7

From the difference of 38.7ºC, there are two interpretations:

  • Regina is 38.7ºC degrees colder in January than in July.
  • Regina is 38.7ºC degrees warmer in July than in January.
