Question

when 1 is subtracted from the five types of number and the result is divided by more than twice of the number we get 4/5 find the number

Answer 1

Hello !!

Let number be X.

5 times of X = 5X

★ subtracting 1 from 5X

5X - 1

Two more than twice of X = (2X + 2)

★ Dividing 5X-1 by (2X + 2 )

=> 5X-1/2X + 2 = 4/5

=> 5 ( 5X - 1 ) = 4 ( 2X+2)

=> 25X - 5 = 8X + 8

=> 25X - 8X = 8+ 5

=> 17X = 13

=> X = 13/17


Number = X = 13/17.

Answer 2

HEYA!!
---------

Let the number be X

Five times X = 5 X

Subtracting 1 from 5 X

5 X - 1 ---------------------------------------------------(1)

2 more than twice of this number = 2X + 2 ----------------(2)

Dividing (1) and (2)

$\frac{5x - 1}{2x + 2} = \frac{4}{5} \\ \\ 25x - 5 = 8x + 8 \\ \\ 17x = 13 \\ \\ x = \frac{13}{17}$
