227/462

Step-by-step explanation:

3/7-6/11+8/21+5/22

so we will first do for 3/7 + 8/21

We will multiply 3/7 by 3/3

We will get 9/21+8/21

then 9+8/21

which is 17/21

now we will do for -6/11+5/22

in which we will multiply -6/11 by 2/2

it will become,-12/22+5/22

then,-7/22

now we have,17/21-7/22

cross multiply, 17×22 -7×21/21×22

which will be 374-147/462

227/462
