Its not that hard.
Half of the inch part is 1/2 inch which is also 4/8.
half of the 3/4 part is 3/8 you get by multiplying the denominator by 2.
Put it all back together and you get the 4/8 part and the 3/8 part so in total its 7/8 of an inch.
Phosphorus pentoxide gets its name from the empirical formula of the compound, which is P2O5. Molecules of P2O5 are unstable and associate with each other to form the larger molecules of P4O10. At room temperature, phosphorus pentoxide is a solid, white waxy substance and is typically a powder.
tricyclo[3.3.1.13,7]tetraphosphoxane 1,3,5,7-tetraoxide
Similarly, how do you write p4o10? P4O10 is technically called tetraphosphorus decaoxide, but under normal conditions it only exists as the dimer of P2O5, which is phosphorus (V) oxide, or phosphorus pentaoxide. The chemical name is for P4O10 is Phosphorus Pentoxide.
