= 7/6 * - 3/7
= 1/2 * - 1
= - 1/2 or
= 7/6 * - 3/7
= - 21/42
= - 1/2
= 1/2 * - 1
= - 1/2 or
= 7/6 * - 3/7
= - 21/42
= - 1/2

Multiply the numerators to be the product's numerator.
Multiply the denominators to be the product's denominator:
(7/6) * (-3/7) = -21/42 = -1/2
Or you can cancel like factors from the top and bottom before doing the multiply:
(7/6) * (-3/7)
(1/2) * (-1) [7's cancel out, and 3's get canceled out]
-1/2

(7/6)(-3/7)
= [7(-3)] / [6(7)]
= -21/42
= (-21 ÷ 21)/(42 ÷ 21)
= -1/2
= [7(-3)] / [6(7)]
= -21/42
= (-21 ÷ 21)/(42 ÷ 21)
= -1/2

7/6 x -3/7
= (7 x -3)/(6 x 7)
= -21/42
= -1/2.
= (7 x -3)/(6 x 7)
= -21/42
= -1/2.
