- -dfrac-45-39- -times -dfrac-13-15- -It can be written as-160- - -dfrac-45 -times -13-39 -times 15- -By further calculation-160- - -dfrac-3 -times -1-3 -times 1- -160-So we get-160- - -dfrac-3-3- -160- - 1 -160-

Evaluate :
$$ \dfrac{-45}{39} \times \dfrac{-13}{15} $$

$$ \dfrac{-45}{39} \times \dfrac{-13}{15} $$
It can be written as
$$ = \dfrac{-45 \times -13}{39 \times 15} $$
By further calculation
$$ = \dfrac{-3 \times -1}{3 \times 1} $$
So we get
$$ = \dfrac{3}{3} $$
$$ = 1 $$
