What fraction can be used in conversion of 32 m3 to mm3

The calculation is (Measurement in m³ x 1000³)

Therefore

Measurement in m³ x 1 000 000

Its not a fraction as there are 1000mm in a m, so to convert from m to mm you must multiply

First, we can determine in simple conversion between meter and millimeters. As the prefix tells us "mili". The difference between then is 1000, so

1 meter= 1000 milimeters

Because the value is a volume and not a unit of length, we have to cube both sides.

(1 m)^3 = (1000 mm)^3

1 m3= 1000000 mm3.

The fraction is 1000000 mm3 / 1 m3

The reaction will shift to the right

B.1 - hydrogren-1 can only mean there is 1 neutron. it's obvious there is 1 proton or else it wouldn't be hydrogen, so they wouldn't put a number after it unless they were indicating the number of neutrons
