3 steps

यहाँ प्रश्न 1 का a) भाग हल किया गया है:

1. तीन समतुल्य परिमेय संख्याएँ लिखिए:

a) −79\frac{-7}{9}

  1. अंश और हर को 2 से गुणा करें.

    −79=−7×29×2=−1418\frac{-7}{9} = \frac{-7 \times 2}{9 \times 2} = \frac{-14}{18}

  2. अंश और हर को 3 से गुणा करें.

    −79=−7×39×3=−2127\frac{-7}{9} = \frac{-7 \times 3}{9 \times 3} = \frac{-21}{27}

  3. अंश और हर को 4 से गुणा करें.

    −79=−7×49×4=−2836\frac{-7}{9} = \frac{-7 \times 4}{9 \times 4} = \frac{-28}{36}

    −79\frac{-7}{9} की तीन समतुल्य परिमेय संख्याएँ हैं: −1418,−2127,−2836\boxed{\frac{-14}{18}, \frac{-21}{27}, \frac{-28}{36}}.
