Solution

step:
Multiplying the Given rational numbers

Given $- \frac{45}{39} \times \frac{- 13}{15}$

$∵ p r o d u c t o f t w o r a t i o n a l n u m b e r s = \frac{P r o d u c t o f t h e N u m e r a t o r s}{P r o d u c t o f t h e D e n o m i n a t o r s}$

$= \frac{- 45 \times (- 13)}{39 \times 15} = \frac{45 \times 13}{39 \times 15}$

$= \frac{15 \times 3 \times 13}{39 \times 15}$
$= \frac{39}{39}$
$= 1$
Hence, the required product is 1.
