Question

which number should be multiplied by minus 5 by 17 to get -2​

Answer 1

Let the number be x

$\frac{-5}{17} × x = - 2 \\ -5x = (-2) × 17 \\ -5x = - 34 \\ 5x = 34 \\ x = \frac{34}{5}$

$So, the \: required \: number is \frac{34}{5}$

Answer 2

Answer:

x = 1/3

Step-by-step explanation:

Let x be multiplied by 5−3 to get 5−1

Then, x × (−3/5) = −1/5

⇒-3x/5 = −1/5

⇒(-3x) × 5 = -1 × 5

⇒-15x = -5

x = 1/3 should be multiplied

⇒x = -5/-15

⇒x = 1/3
