Answer:
The decimal multiplier to decrease by 39% is 0.61.
Step-by-step explanation:
Decimal multipliers:
For a increase of a%, the decimal multiplier is given by [tex]\frac{100+a}{100}[/tex]
For a decrease of a%, the decimal multiplier is given by [tex]\frac{100-a}{100}[/tex]
Decrease of 39%
So [tex]a = 39[/tex], and:
[tex]\frac{100-a}{100} = \frac{100-39}{100} = \frac{61}{100} = 0.61[/tex]
The decimal multiplier to decrease by 39% is 0.61.
