Answer:
it depends
Step-by-step explanation:
For positive powers of 10, the decimal point moves right 1 place for each zero in the power of 10.
<u>Example</u>:
1.2345 × 10³ = 1.2345 × 1000 = 1234.5 × 1 = 1234.5
__
For negative powers of 10, the decimal point moves left 1 more place than there are zeros in the power of 10.
<u>Example</u>:
1234.5 × 10⁻³ = 1234.5 × 0.001 = 1.2345
there are 2 zeros in .001, but the decimal point moves 3 places, corresponding to the exponent of 3 in the power of 10.
Basically the line (/) means divide so basically 1 divided by 400 but we need a percentage so 1/400 = 0.0025 which will be 0.25%
Hope this helps this is as much as I can really explain it.
