Question

the product of two number is minus 5 whole -5 by 12 .If one number is 1 whole 2 by 13 find the other number

Answer 1

$1 \times( \frac{2}{13} ) \times x = - 5 \times( \frac{ - 5}{12} ) \\ = \frac{15}{13} \times x = \frac{65}{12}$
then 15*12x=13*65
180x=845
x=845/180=169/36
$4 \times \frac{25}{36}$
