Explanation:

express 3/5 as a rational with denominator -20

Ans:--12/-20

Answer 2

$\star\Huge\mathfrak\blue{ANSWER }\star$

$\Huge\mathfrak\red{-12: - 20}$

$\Huge\mathfrak\green{Now\: let's\: do\: it \:step\: by \:step}$

$\Huge\mathfrak\purple{as\: we\: know\: that \:we\: can \:treat \: rational \: no. \: as fractions \: only}$

$\Huge\mathfrak\red{so \: now \: lets \: solve \: it }$

$\Huge\mathfrak\green{5and-20 are denominators so result should be - 20 so we will divide 5 by-20 }$

$\Huge\mathfrak\red{5÷-20 =5÷20=4÷-1=-4}$

$\Huge\mathfrak\purple{so x =-4}$

$\Huge\mathfrak\green{3/5×-4=y/-20</p><p>Now we will find y}</p><p>$

$\Huge\mathfrak\red{So \: for \: that \: we \: will \: multiply \: numerator \: with \: the \: same \: no. \: And \: the \: result \: will \: be \: the \: value \: of \: y}$

3/5×-4=12/-20
