помогите

Answer 1

1 1/2 * (-5) * (-2/3) = 3/2 *(-2/3) * (-5) = -1 *(-5) = 5

3/8 * (-13) * 2 2/3 = 3/8 * 8/3 * (-13) = 1 *(-13) = -13

-1 3/7 * (-9) * (-7/10) = -10/7 * (-7/10) * (-9) = 1 * (-9) = -9

Answer 2

11/2*(-5)*(-2/3)=3/2*(-2/3)*(-5)=1*(-13)=5
3/8*(-13)*22/3=3/8*8/3*(-13)=1*(-13)=-13
-13/7*(-9)*(-7/10)=10/7*(-7/10)*(-9)=-1*(-9)=9
