प्रश्न
`(-3)/7 ÷ ((-7)/3)` = ______.
उत्तर
`(-3)/7 ÷ ((-7)/3) = bb(underline(9/49)`.
Explanation:
∵ Reciprocal of `(-7)/3` is `3/(-7)`
∴ `(-3)/7 xx (3/(-7))`
Product of rational numbers = `"Product of numerators"/"Product of denominators"`
= `((-3) xx 3)/(7 xx (-7))`
= `(-9)/(-49)`
= `9/49`
Hence, `(-3)/7 ÷ ((-7)/3) = 9/49`.
