Answer 1

Answer:

Step-by-step explanation:

Let the actual number be x

Now it's 3x/4

Therefore reduce percentage is

((3x/4)/x)*

=(3/4)*100

=75 percent

Answer 2

Answer:

25%

Step-by-step explanation:

Let the number be x

$\frac{3}{4}$ × x= $\frac{3x}{4}$

Decrease= x -    $\frac{3x}{4}$  ⇒ $\frac{4x-3x}{4}$ = x/4

Decrease percent= Decrease/Original value x 100= ( $\frac{x}{4}$ ÷ x) × 100

($\frac{x}{4}$ × $\frac{1}{x}$) × 100⇒ 1/4 × 100 = 25%
