The number that should be multiplied by $\frac{-87}{98}$ so that the the product is 17.

$\large{ \pmb{ \sf{ \underline{Solⁿ :}}}}$

Let the number be x.

Now,

${ \sf{ = > \frac{ - 87}{98} \times x = 17}}$

${ \sf { = > \frac{ - 87x}{98} = 17}}$

${ \sf {= > - 87x = 17 \times 98}}$

${ \sf{ = > - 87x = 1666}}$

${ \sf{ = > -x = \frac{ \cancel{1666}}{ \cancel{87} }}} = 19.14$

${ \sf { = > x = - 19.14}}$

${ \pmb{ \sf{ \boxed{ \pink{x = -19.14 (approx.)}}}}}$

${ \pmb{\sf{ \blue{Hence, \: the \: number \: is \: -19.14 \: (approx.)}}}}$
