56 is the lcd of 8 and 7. You can get this by multiplying 8x7. 8 and 7 have no common factors; that is why you multiply the two numbers to get the lcd.

LCD(7, 8, 2) = 56.

LCD(15, 7, 8) = 840.

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

4 and 7 over 8 as a percent = 487.5% 4 and 7 over 8 = 4 7/8 or 39/8 39/8 * 100% = 3900%/8 = 487.5%

Because there is a smaller number (least) than 32 (4 x 8). The LCD is 8.

5/8 / 4/7 = 5/8 * 7/4 = 5*7 / 8*4 = 35 / 32

LCD(4, 8, 11) = 88.

2 8/7 divided by 4/7 is the same as 8/7 times 7/4... The 7s then cancel out and you get 8/4 which is 2
