What are percentage?

percentage is the ratio of composition of matter to the overall composition of matter multiplied by 100.

1) Decrease 1.25km by 0.6%
    0.6% of 1.25km = 0.0075
    so total decrease = 1.25 - 0.0075
             = 1.2425
similarly,
2.) Decrease 64 g by 12 ½%
  12 ½% of 64g = 8g
   so total decrease = 64-8

                                 = 56g

3. Decrease 124 L by 15%
          15% of 124 = 18.6L
     so total decrease = 105.4L

4. Decrease 350m² by 42%
  42% of 350m² =  147m²
    so total decrease = 203m²

Thus, the required decreased value is given by 1.2425, 56g, 105.4L, 203m²
