Answer:
34/21
Step-by-step explanation:
Given That ,
= 2/3+6/7-1/3+3/2+5/2-4/7-3
= [ (2×14)+(6×6)+(-1×14)+(3×21)+(5×21)+
(-4×6)+(-3×42) ] /42
[ Because LCM of 3,7,3,2,2,7,1 is 42]
= [ 28+36-14+63+105-24-126 ] / 42
= 68/42
= 34/21 [ Because 2×21=21 and 2×31=68]
Hence, 2/3+6/7-1/3+3/2+5/2-4/7-3 = 34/21
