Question

Three numerical expressions that are equivalent to (0.0004) x (0.005)

Answer 1

Numerical expression 1

`(4)/(10000) * (5)/(1000) = (20)/(10000000) = (1)/(500000)`

Numerical expression 2

`(1)/(50000) = 0.2 * 10^(-4) = 2 * 10^(-5)`

Numerical expression 3

`1 : 50000`

Explanation:

Numerical expression 1

`(4)/(10000) * (5)/(1000) = (20)/(10000000) = (1)/(500000)`

Numerical expression 2

`(1)/(50000) = 0.2 * 10^(-4) = 2 * 10^(-5)`

Numerical expression 3

`1 : 50000`
