Question

How do you simplify `0.5 div 0.001`?

Answer 1

`500`

Explanation:

Rewrite both decimals as fractions.

`0.5 = 1/2` and `0.001 = 1/1000`

`1/2 divide 1/1000`

Dividing by a fraction is the same as multiplying by the reciprocal (switch the numerator and denominator).

`1/2 times 1000/1`

`(1times1000)/(2times1)`

`1000/2`

`500`
