Question

Express - 42 by 98 as a rational number with denominator 7​

Answer 1

-3/7 is the rational number with denominator 7

Answer 2

Answer:

$\frac{- 3 }{ 7 }$

Step-by-step explanation:

we have to split the denominator in such a way that we get 7 as one of the denominator factor

            $\frac{-42}{98}$      =        $\frac{-42}{ 14 * 7 }$

now try to cancel out everything other than 7 in denominator because we only need 7 in denominator place

      = $\frac{- 14 * 3 }{ 14 * 7 }$     14 will be cancelled out from both     numerator and denominator

= $\frac{- 3 }{ 7 }$

                                 $\frac{- 3 }{ 7 }$
