8 times 5 is 40, and 40 times 7 is 280.

It is equal to:
5 x 7 x 8 = 280

280
2 1/5+ 1 3/7+ 6 1/8
2 56/280+1 40/280+ 6 35/280= Add all the fractions then just add the whole numbers to that.

the smallest common denominator I can find is 280 so is would be :
2 56/280 + 1 120/280 + 6 35/280 = 9 211/280, or translated to a decimal would be 9.754

continuously commence with the optimal denominater, which therefore is 8, and multiply it through a million,2,3 and so on till you get to a volume that the different denominators (4 and 5) can bypass into with none remainders... So, 8*a million= 8, no cuz 4 and 5 doesnt bypass into 8 gently 8*2=16, no cuz 4 might want to bypass into 16 gently, yet no longer 5 8*3=24 no, same causes... 8*4=32 no, same causes... 8*5=40 Bingo! both 4 and 5 bypass into this gently, so 40 is your lcd.

i am not so sure what u mean.
if u want their common denominator, it is 5*7*8 = 280,
not sure about the equation u wrote though

9 211/280 I think. I used a whole piece of paper trying to figur this one out.
