\(\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{2}{5}+\dfrac{5}{7}+\dfrac{1}{6}-\dfrac{4}{35}\)

\(=\left(\dfrac{1}{2}+\dfrac{1}{3}+\dfrac{1}{6}\right)+\left(\dfrac{2}{5}+\dfrac{5}{7}-\dfrac{4}{35}\right)\)

\(=1+1=2\)

Mình thấy cũng hay nhưng mà ở chỗ phần ba ngàn một ổ , bốn ngàn một ổ nghe chưa hay lắm vì nó hơi giống nhau 

                                                        ( mình nhận xét thật lòng, mong các bạn **** với lại mình cũng đã có kinh viết thơ rùi )

\(\dfrac{2}{3}-\dfrac{3}{4}+\dfrac{7}{12}-\dfrac{5}{6}+1\)

\(=\dfrac{8}{12}-\dfrac{9}{12}+\dfrac{7}{12}-\dfrac{10}{12}+\dfrac{12}{12}\)

\(=\dfrac{8-9+7-10+12}{12}\)

\(=\dfrac{8}{12}=\dfrac{2}{3}\)

Ta có:

a/b : 18/35 =x => a/b = 18x/35

a/b : 8/15  = x => a/b =8y/15

=> 18x/35 = 8y/15

=> 54x/105 = 56x/105

=>54x=56y, x và y nhỏ nhất

=> 27x=28y;vì 27 và 28 nguyên tố cùng nhau nên x=28 và y=27

=> a=72;b=5

a+b=72+5=77
