`(-20)/12, 5/3`
`16/(-30), (-8)/15`
`(-18)/36, (-20)/44`
`7/(-5), (-5)/7`
उत्तर
`16/(-30), (-8)/15`
Explanation;
Hint:
`(-20)/12 = (-20 ÷ 4)/(12 ÷ 4) = (-5)/3 ≠ 5/3`
`16/(-30) = (-16 ÷ 2)/(30 ÷ 2) = (-8)/15`
`(-18)/36 = (-18 ÷ 9)/(36 ÷ 9) = (-2)/4`
= `(-2 xx 11)/(4 xx 11)`
= `(-22)/44 ≠ (-20)/44`
∴ `16/(-30)` and `(-8)/15`
