Answer 1

Answer:

(-7)×1×(-5) is greater than (-7)×(-1)×(-5)

Step-by-step explanation:

(-7)×1×(-5) = 7×5 ( because minus÷minus is plus)

=35

(-7)×(-1)×(-5) = 7×(-5) (because minus×minus is plus)

= -35 (because plus×minus is minus)

35>-35

Answer 2

$Here, i) (-7) \times (-5) \times (-1) \\=[ (-7) \times (-5)] \times (-1)\\= 35 \times (-1) \\= -35 \: --(1)$

$ii ) (-7) \times 1 \times (-5) \\= [(-7) \times 1] \times (-5) \\= (-7) \times (-5) \\= 35 \: -- (2)$

/* From (1) and (2) , we conclude that */

$35 \pink {> }(-35)$

$\therefore (-7) \times 1 \times (-5) \pink { > } (-7) \times (-5) \times (-1)$
