1. here is ur answer•♪

   Answer:

   Percent (%)’ means ‘out of one hundred’:

   p% = p ‘out of one hundred’,

   p% is read p ‘percent’,

   p% = p/100 = p ÷ 100.

   – 25% = – 25/100 = – 25 ÷ 100 = – 0.25.

   100% = 100/100 = 100 ÷ 100 = 1.

   Decrease number by – 25% of its value.

   Percentage decrease = – 25% × – 24

   To decrease a negative number, do not subtract from it,

   but add the ‘percentage decrease’.

   New value = – 24 + Percentage decrease

   Calculate the New Value

   New value =

   – 24 + Percentage decrease =

   – 24 + (- 25% × – 24) =

   – 24 – 25% × – 24 =

   (1 – 25%) × – 24 =

   (100% – 25%) × – 24 =

   75% × – 24 =

   75 ÷ 100 × – 24 =

   75 × – 24 ÷ 100 =

   – 1,800 ÷ 100 =

   – 18

   Calculate absolute change (actual difference)

   Absolute change (actual difference) =

   New value – (- 24) =

   – 18 – (- 24) =

   – 18 + 24 =

   6

   Proof.

   Calculate percentage decrease:

   Percentage decrease =

   – 25% × – 24 =

   – 25 ÷ 100 × – 24 =

   – 25 × – 24 ÷ 100 =

   600 ÷ 100 =

   6

   For negative numbers

   Absolute change (actual difference) =

   Percentage decrease

   Answer:

   – 24 decreased by – 25% = – 18

   Absolute change (actual difference):

   – 18 – (- 24) = – 18 + 24 = 6
