Question

if 80 is decreased by 40 percent, find the decreased number.​

Answer 1

Answer:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Decrease number by 40% of its value.

Percentage decrease = 40% × 80

New value = 80 - Percentage decrease
