Problema Solution
Mr. Enriquez bought 15 hectares from Mr. Santos' square kilometer piece of land. What part of the original land is left with Mr. Santos?
Answer provided by our tutors
we use a conversion factor of 1 hectare = 0.01 kilometers squared
1 - 15(0.01/1) = 0.85
0.85 square kilometers is still left with Mr. Santos
conversion to hectares:
0.85 * 1/(0.01) = 85 hectares
this leaves 85 hectares still left with Mr. Santos
