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)
I think what you might have meant was LCD (Lowest Common Denominator) The LCD for 11/7 and 3/8 is 56 Making equivalent fractions using the LCD: 11/7 becomes 88/56 3/8 becomes 21/56
LCD(15, 7, 8) = 840.
Because there is a smaller number (least) than 32 (4 x 8). The LCD is 8.
