5)3/8*(-13)* 2 2/3
6)-1 3/7*(-9)*(-7/10)

Answer 1

1)
 - ³/₄ * 7 * (- 1 ¹/₃) = (³/₄ * ⁴/₃) * 7 =  1 * 7 =7
2)
⁵/₆ * (-8) * ³/₅ = (⁵/₆ * ³/₅) * (-8) = ¹/₂ * (- 8) = - ⁸/₂ = - 4
3)
- ⁵/₉ * (-11) * 1 ⁴/₅ = (⁵/₉ * ⁹/⁵) * 11 = 1 * 11 = 11
4)
1 ¹/₂ * (-5) * (- ²/₃) = (³/₂ * ²/₃) * 5 = 1 * 5 = 5
5)
³/₈ * (-13) * 2 ²/₃ = (-13)* (³/₈ * ⁸/₃) = - 13 - 1 = - 13
6)
-1 ³/₇ * (-9) * (- ⁷/₁₀) = -  9 * (¹⁰/₇ * ⁷/₁₀) = - 9 * 1 = - 9
