Question

What is 64 decreased by 25% ?

Answer 1

Step-by-step explanation:

'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% × 64

New value = 64 - Percentage decrease

Calculate the New Value

New value =

64 - Percentage decrease =

64 - (25% × 64) =

64 - 25% × 64 =

(1 - 25%) × 64 =

(100% - 25%) × 64 =

75% × 64 =

75 ÷ 100 × 64 =

75 × 64 ÷ 100 =

4,800 ÷ 100 =

48
