Here's a good way to think about it - fractions are just division, right? So, just like with multiplication, the order doesn't matter. In other words, 3/10 of 1/2 meter is the same as 1/2 of 3/10 of a meter (just like 3 x 2 = 2 x 3).

So what is 1/2 of 3/10? well you could say it is 1.5/10 (divide your 3/10 by 2 to get 1.5/10), OR you could say 3/20 (dividing by 2 in the numerator is the same as multiplying by 2 in the denominator).

So 3/10 of 1/2 of a meter is 3/20 of a meter. 3/20 of 100cm = (100)*3/20.

Well 300/20 = 15 soo 3/20 of a meter is 15cm.
