LCM = 5 × 3 × 3 × 7 × 2 × 2 × 5
LCM = 6300
<u>Hence, the LCM of 315 , 420 , 525 is 6300</u>
The answer is 12
12-(5+3)=4
4+8=12
It's just 24.53 because the hundredth place is the 3, but the value after it is not high enough to round it up. Therefore, the answer is 24.53
4x/15 = 60/x
4x^2 = 900
x^2 = 225
x = 15
