Question

the product of two rational number is 15/56 if one of the number is -54/8, find the other

Answer 1

$\frac{ - 54}{8} \times x = \frac{15}{56}$

$x = \frac{ {}^{5} \cancel 15}{ _{7} \cancel{56}} \times \frac{ \cancel8}{ \cancel{ - 54} _{ - 18} }$

$x = \frac{5}{ - 126} = \frac{ - 5}{126}$
