The sum is 23/30

1 1/4 or one and a quarter or 1.25

5 1/12

5 + 3 1/6 = 8 1/6 or eight and one sixth.

11/30

11/15

2/5 plus 1/5 minus 3/10 is equal to 0.3 or 3/10

Answer is ten and eleven thirtieths. Found by making the denominators the same at thirty and then adding.

1 3/6

one third plus one quarter plus one fifth plus one sixth plus six = 6 57/60 1/3 + 1/4 + 1/5 + 1/6 +6: = (20 + 15 + 12 + 10)/60 + 6 = 57/60 + 6 = 6 57/60

well three-sixth-two-sixth is one-sixth

ONE

it's 2/3 (two thirds)

(1/6) + (3/8) = (4/24) + (9/24) = 13/24

5/6

7 and 1 6th Seven and one sixth

Since five fifths equal one whole, 6/5 would equal one whole plus one fifth. So 7 plus 1 and one fifth is 8 and 1 fifth or 8 1/5

(1/5) + (2/6) = (8/15)

7 15ths

11 over 18

3/15 is equal to 1/5, therefore, 1/5 plus 1/5 would equal 2/5

1/5 + 3/5 + 1/5 = 1

8/15
