Bobby made a big batch of soup weighing 80 kg. Each day the batch gets reduced by half. How many kg will it reach on the fourth day after he made the soup?
On the first day, the soup reduces down to 80/2=<<80/2=40>>40 kg.
On the second day, it reduces down to 40/2=<<40/2=20>>20 kg.
On the third day, it is reduced to 20/2=<<20/2=10>>10 kg.
And on the fourth day, it is finally down to 10/2=<<10/2=5>>5 kg.
