Question

what no should subtracted from -8/5 to get -2​

Answer 1

Answer:

Let x be the unknown number

$- \frac{8}{5} - x = - 2$

$\frac{ - 8 - 5x}{5} = - 2$

$- 8 - 5x = - 10$

$- 5x = - 10 + 8$

$- 5x = - 2$

cancelling - on both the sides

$x = \frac{2}{5}$

Verification:

$- \frac{8}{5} - \frac{2}{5} = 0$

$- \frac{10}{5} = 0$

if u cancel this u will get - 2

it means that 2/5 is the correct answer

Answer 2

Let the number be x

According to the question

$\frac{ - 8}{5} - x = - 2 \\ \frac{ - 8}{5} + 2 = x \\ \frac{ - 8 + 10}{5} = x \\ \frac{2}{5 } = x \\ x = \frac{ 2}{5}$
