When a number is decreased by 20% of itself, the result is 56 what is the number?
coldgirl [10]

Hey there!!

Let us take the number as ' x '

20% of x

= (20/100) × ( x )

= ( 1/5 ) × ( x )

= x/5

The number is decreased by 20% of itself

x - x/5 = 56

5x - x / 5 = 56

4x/5 = 56

Multiplying by 5 on both sides

5x = 56 × 5

5x = 280

dividing by 5 on both sides

4x / 4 = 280 / 4

x = 70

The number is 70

Hope my answer helps!

The repeating decimal, 0.27..., is converted to the fraction 0.27..=3/x
marysya [2.9K]

Answer:

The value of x is 11.

Step-by-step explanation:

The given number is 0.27272727..., and it is converted to the fraction as

0.272727...=\frac{3}{x}                 ..... (1)

Multiply both sides by 100.

0.272727...\times 100=\frac{3}{x}\times 100

27.272727=\frac{300}{x}            .... (2)

Subtract equation (1) from equation (2),

27.272727-0.272727...=\frac{300}{x}-\frac{3}{x}

27=\frac{300-3}{x}

Multiply both sides by x.

27x=297

Divide both sides by 27.

x=\frac{297}{27}

x=11

Therefore the value of x is 11.
