<span>LCM(7,18,21) </span>Least Common Multiple is :<span> 126 </span>
Calculate Least Common Multiple for :
7, 18 and 21
Factorize of the above numbers:<span> 7 = 7
<span> 18 = 2 • 32 </span>
<span> 21 = 3 • 7 </span></span>
<span> -2 is the opposite of 2
--------------------------------------
-1/2 is the opposite of 1/2.</span>
is it 11/8 or 1 and 1/8?
if it is 11/8 divide 11 by 8, 11/8 = 1.375
if it is 1 and 1/8 divide 1 by 8, 1/8 = 0.125 then add it to the 1
so 1 and 1/8 = 1.125
(p + 6)/8 = (p - 6)/7
7(p + 6) = 8(p - 6)
7p + 42 = 8p - 48
8p - 7p = 42 + 48
p = 90
