It is: 315
315
LCD(21, 45) = 315
21% of 315= 21% * 315= 0.21 * 315= 66.15
The LCM of 315 and 9 is 315
9 = 3^2 15 = 3 x 5 21 = 3 x 7 lcm = 3^2 x 5 x 7 = 315
315% = 3.15 315 = 31,500%
315
The Least Common Multiple (LCM) of (5,9,7) is 315.The LCM of 5, 7, and 9 is 315.
The LCM is: 315
35.4635
36% of 315 = 113.4 = 36% * 314 = 36%/100% * 315 = 0.36 * 315 =113.4
