What is the lcm of 3,5,4

Anytime! (:

Least common multiple? 

2x3=6 
3x3=9 
4x3=12 
5x3=15 
6x3=18 
7x3=21 
8x3=24 
9x3=27 
10x3=30 
... 
20x3=60 

1x4=4 
2x4=8 
3x4=12 
4x4=16 
5x4=20 
6x4=24 
7x4=28 
8x4=32 
9x4=36 
10x4=40 
11x4=44 
12x4=48 
13x4=52 
14x4=56 
15x4=60 

1x5=5 
2x5=10 
3x5=15 
4x5=20 
5x5=25 
6x5=30 
7x5=35 
8x5=40 
9x5=45 
10x5=50 
11x5=55 
12x5=60 

LCM is 60 because that's where all multiples of each factor are first equal.

What I just said, makes any since to you?

Yes thank you again 

Let me add one thing here.......if we have some list of numbers that are relatively prime to each other  [ they have no factors in common], the LCM   will just be the product of those numbers

Notice that  3 and 5 are prime - they couldn't share any factors - and 4 doesn't have any factors in  common with either of them.....so  the LCM  =  3 * 4 *  5   =   60

How do u do percentage? I just dont get it...... for example

What is 50% of 100 or What is 25% Of 200

It is very simple. Any time you see a number followed by %, such as 50%, it means this:

50% means: 50/100 =0.50. So 50% of 250 =50/100 x 250 =0.50 x 250 =125.
