Hi Marknassar,

You're missing the fact that there is a multiplication on the numerator, so there are 6 decimals after the decimal point on the numerator.
This way, you need to move the decimal point in the denominator to 6 decimals as well.

(0.625 x 0.008) / 0.01 = 625 x 8 / 10,000 = 5,000 / 10,000 = 5 / 10 = 0.5

Hope it helps!

Thanks! Ale :-)
