Question

Percent increase and decrease. Original number:45 New number: 18

Answer 1

60% decrease

Explanation:

To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%

here the decrease = 45 - 18 = 27

percent decrease =
`(decrease)/(original)` × 100%

=
`(27)/(45)` × 100% = 60%
