Plz solve this sum step by step
correctly !​

Answer 1

Answer:

(-4/5)+[(7/6)(7/7)]+[(2/7)(6/6)]+3+(-11/6)=

(-4/5)+[(49/42)+(12/42)]+3+(-11/6)=

(-4/5)+[(49+12)/42]+3+(-11/6)=

(-4/5)+(61/42)+3+(-11/6)=

(-4/5)+[(61/42)]+[3(42/42)]+(-11/6)=

(-4/5)+(61/42)+(126/42)+(-11/6)=

(-4/5)+[(61+126)42]+(-11/6)=

(-4/5)+(187/42)+(-11/6)=

(187/42)+[(-4/5)(6/6)+(-11/6)(5/5)]=

(187/42)+[(-24/30)+(-55/30)=

(187/42)+(-79/30)=

[(187/42)(30/30)]+[(-79/30)(42/42)]=

(5610/1260)+(-3318/1260)=

(5610-3318)/1260=

2292/1260

=191/105

Answer 2

Answer:

389/210

Step-by-step explanation:

-4/5+7/6+2/7+3+-11/6

= (-4/5+ -11/6)+(7/6+2/7+3/1)

= (-24/30+ -55/30)+(49/42+12/42+126/42)

= -78/30+187/42

= -546/210+935/210

= 935-546/210

=389/210
