First you have to find the LCD. LCD=40
Then you multiply each fraction top and bottom to get 40 as the LCD. 35/40+32/40+18/40
Then you need to add. 85/40
Lastly you simplify. So the answer is 19/8(19 over 8)
1 and 1 over 20
15/20 or 3/4
3/20 + 4/5 = 19/20note:4/5 * 4/4 = 16/20thus, 3/20 + 16/20 = 19/20
The sum of 4/5 and 6/20 = 1 1/10
4/20 + 2/13 = 92/260 or 23/65
1 and 1 over 20
15/20 or 3/4
3/20 + 4/5 = 19/20note:4/5 * 4/4 = 16/20thus, 3/20 + 16/20 = 19/20
4/20 + 2/13 = 92/260 or 23/65
The sum of 4/5 and 6/20 = 1 1/10
15 OVER 20
25/20 or 1 and 1/4
16/20 + 6/20 + 17/20 = 39/20 = 1 and 19/20
1 13/20
0.85 or 17/20
The sum of 4/20 and 2/13 is 23/65
