Пошаговое объяснение:
1) -14/15 × 25/28 + (-36/37) ÷ (-6/37)=5 1\6
-14/15 × 25/28=-5\6
(-36/37) ÷ (-6/37) =-36\37*(-37\6)=6
-5\6+6=5 1\6
2) 26/27 × (-9/65) + (-100/101) ÷ 50/303 =-6 2\15
26/27 × (-9/65)=-2\15
(-100/101) ÷ 50/303 =-100\101*303\50=-6
-2\15+(-6)=-6 2\15
3)-30/31 × 15/124 + (-16/21) × (-7/8)=173\372
-30/31 × 15/124 =-25\124
(-16/21) × (-7/8)=2\3
-25\124+2\3=-75\372+248\372=173\372
4) (-51/58) ÷ (-17/25) - 25/27 × (-81/125)=-201\290
(-51/58) ÷ (-17/25) =-51\58*(-25\17)=-75\58
25/27 × (-81/125)=-3\5
-75\58-(-3\5)=-375\290+174\290=-201\290
