Question

Find the decreased value if 1300 is decreased by 20% *
​

Answer 1

Answer:

Decrease number by 20% of its value.

Percentage decrease = 20% × - 1,300

To decrease a negative number, do not subtract from it, but add the 'percentage decrease'.

New value =

- 1,300 + Percentage decrease =

- 1,300 + (20% × - 1,300) =

- 1,300 + 20% × - 1,300 =

(1 + 20%) × - 1,300 =

(100% + 20%) × - 1,300 =

120% × - 1,300 =

120 ÷ 100 × - 1,300 =

120 × - 1,300 ÷ 100 =

- 156,000 ÷ 100 =

- 1,560
