\(A=\frac{67^{2016}}{67^{2016}}-11=1-11=-10< 0\)

\(\Rightarrow A< 0\)

\(B=\frac{67^{2016}+3}{67^{2016}+2}>0\)

\(\Rightarrow B>0\)

Vậy \(B>A\)

bằng 1/3 bạn nhé ..check mk đó.

\(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)

\(=\frac{1}{3}+\frac{12}{67}+\frac{13}{41}-\frac{79}{67}+\frac{28}{41}\)

\(=\left(\frac{12}{67}-\frac{79}{67}\right)+\left(\frac{13}{41}+\frac{28}{41}\right)+\frac{1}{3}\)

\(=\left(-1\right)+1+\frac{1}{3}\)

\(=\frac{1}{3}\)

bằng \(\frac{1}{3}\)nhé

\(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\\ =\left(\dfrac{103}{201}+\dfrac{13}{41}\right)-\dfrac{1363}{2747}\\ =\dfrac{6836}{8241}-\dfrac{1363}{2747}\\ =\dfrac{1}{3}\)

\(\left(\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}\right)-\left(\dfrac{79}{67}-\dfrac{28}{41}\right)\\ =\dfrac{1}{3}+\dfrac{12}{67}+\dfrac{13}{41}-\dfrac{79}{67}+\dfrac{28}{41}\\ =\dfrac{1}{3}+\left(\dfrac{12}{67}-\dfrac{79}{67}\right)+\left(\dfrac{13}{41}+\dfrac{28}{41}\right)\\ =\dfrac{1}{3}-\dfrac{67}{67}+\dfrac{41}{41}\\ =\dfrac{1}{3}-1+1\\ =\dfrac{1}{3}\)

\(\left(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}\right)-\left(\frac{79}{67}-\frac{28}{41}\right)\)

=\(\frac{1}{3}+\frac{12}{67}+\frac{13}{41}-\frac{79}{67}+\frac{28}{41}\)

\(=\frac{1}{3}+\left(\frac{12}{67}-\frac{79}{67}\right)+\left(\frac{13}{41}+\frac{28}{41}\right)\)

\(=\frac{1}{3}-1+1\)

\(=\frac{1}{3}\)

(1/3+12/67+13/41)-(79/67-28/41).    =1/3+12/613/41-79/67+28/41.        =1/3+(12/67-79/67)+(13/41+28/41) =1/3+(-1)+1=1/3+0.   =1/3

34/79 + 78/67 xấp xỉ 1.6 nha bạn

34/97 + 65/34 = 7461/3298

1/3 + 27/67 = 148/201

a) 67 x 3 + 67 x 7

= 67 x (3 + 7)

= 67 x 10

= 670

b) 45 x 6 + 45 x 4

= 45 x (6 + 4)

= 45 x 10

= 450

c) 27 x 6 + 73 x 6

= 6 x (27 + 73)

= 6 x 100

= 600
