If that's 3/8 and 7/10, the LCD is 40.If not, it's 13490
LCD(32, 40) = 160
LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320LCD(33, 40) = 1320
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 = 1/1, 40 = 40/1 so LCD(1, 40) = 1.
LCD(5, 18) = 90
The least common denominator (LCD) is 40.
LCD(40, 50) = 200
LCD of 7 and 37 is 259.
LCD(63, 7) = 63.
lcd(7, 97) = 679.
LCD(7, 4) = 28
