Multiply everything by thousand to make into whole no. Then divide by factors.

2    100  250  125
2    50    125  125 
25  25     125  125
5     1        5      5
5     1        1      1

Now that there are all ones in the end, multiply all the factors on the left.

This is 2*2*25*5*5
This equals to 2500 .
We multiplied everything by 1000 in the beginning, so now we have to divide it by 1000. That then becomes 2.5. The lcm of 0.25, 0.1 and 0.125 is 2.5. so, at 2.5 seconds, the bells will toll together again.
