dividing by less than one
hi,

first of all i need to say that im really bad in math...
im trying to figure out whats the best way to calculate a whole number divided by numbers smaller than 1...

for ex: 1 divided by 0.00101

how can you make this calculation without using an calculator???

You can multiply the numerator and the denominator by the same number without changing the ratio. So, $\frac{1}{0.00101}=\frac{1\cdot100000}{0.00101\cdot 100000}=\frac{100000}{101}$.
