6/11 + 3/11 = 9/11.
When adding fractions, you must first make sure they have the same denominator (bottom number), then add the top numbers (numerators). The denominator stays the same.
If they do not have the same denominator, you can cross multiply to get to a common denominator.
1/2 x 6/11 = 6/22 =3/11
6 and 3/11 = (6*11 + 3)/11= (66 + 3)/11 = 69/11.
6/11 of 22 is 12
132
Divide 3/5 (.6) and 6/17 (.5454545454545454545454545454545 etc.) 17 and 3/5 is greater because .6 is greater than .5454545454 etc.
6 + 6 + 8 + 3 = 23
2.5 plus 6 plus 3 equals 2.5 plus 6 plus 3
3 + 3 + 3 + 6 + 9 = 24
0.5454545455 . . .

6/11 * 121 = 66
No, because if you give them a common denominator, 3/7 turns into 33/77, and 6/11 turns into 42/77. So six elevenths is larger than three sevenths.
