In yellow, there are only 151 pokemon, number 151 is mew.
The Sinnoh Pokedex only has 151 Pokemon in it.
Number 151 is Manaphy which you can see by looking at the book at the back of Mr.Backlots room in the Pokemon mansion south of Hearthome city. Number 152 is Rotom, which you can see by looking at the T.V in the Old Chateau between 8pm and 3:59am.
151 is Manphy 152 is rotom (catch it in the old house in the forest. at night talk to the TV)
Pokemon number 151 is Manaphy
#151 in the sinnoh pokedex is rotom. you can find him at the old chateau at night in a TV. #152 in the sinnoh pokedex is manaphy. manaphy cannot be obtained directly in platinum, if I'm not mistaken. you'll need to play Pokemon ranger. #151 and 152 in the NATIONAL pokedex however, is mew and chikorita...
152/1 = 152, a whole number. You could write it as 151 and 1/1, but it's kind of pointless.
= 152
In the sinnoh pokedex rotom is number 152 but in the national pokedex rotom is number 479 and chickorita is number 152
The 152nd Pokemon is Chikorita.
