Answer 1

$\huge\mathfrak\red{question}$

Krishna thinks of a number and subtracts 2/9 from it and multiplies by 9 he got 7 times the original number. find the original number.

$\huge\mathfrak\blue{Soultion}$

let the number be x

given,

$(x - \frac{2}{9} ) \times 9 = 7x$

$\frac{9x - 2}{9} = \frac{7x}{9}$

$\frac{9x}{9} - \frac{2}{9} = \frac{7x}{9}$

$\frac{9x}{9} - \frac{7x}{9} = \frac{2}{9}$

$\frac{2x}{9} = \frac{2}{9}$

$x = 1$

Answer 2

Answer:

The answer is 1

Step-by-step explanation:

Let the number Krishna thought of be the variable x

when we subtract 2/9

we get x-2/9

multiplying by 9

we get 9 (x-2/9)

the result would be seven times the initial number that is 7x

so the final equation would be

9 (x-2/9) =7x

9x - 2 = 7x

9x - 7x = 2

2x = 2

x = 1
