Can you answer it for me?

Answer 1

Answer:

Step-by-step explanation:

→  what rational number should -5/43 be multiplied to get 20

let  that rational number be x

→ -5/43 × x=20

→ -5x/43=20

→ -5x= 43 × 20

→ -5x = 860

→ -x = 860/5

→ -x = 172

→ x = -172

Answer 2

Answer:

Step-by-step explanation:

Let the no. be x

A. T. Q.

-5/43 *x = 20

x = 20 /(-5/43)

x = 20 * (-43/5)

x = 4 * (-43)

x = -172

Hence (-172) must be multiplied by (-5/43) to get 20
