The given reaction is an acid-base reaction (neutralisation)

C a C O_{3}

is a base,

H_{3} P O_{4}

is an acid.

Calcium carbonate 3 C a C O_{3} + Phosphoric acid 2 H_{3} P O_{4} \to Calcium phosphate C a_{3} (P O_{4})_{2} + Carbonic acid 3 H_{2} C O_{3}

or

Base 3 C a C O_{3} + acid 2 H_{3} P O_{4} \to C a_{3} (P O_{4})_{2} + 3 C O_{2} + 3 H_{2} O

Calcium carbonate reacts with phosphoric acid to produce calcium phosphate, carbon dioxide and water.
Here,

a = 3, b = 2, p = 1, q = 3, r = 3

Now ratio of

\frac{a}{b}

is

\frac{3}{2}

.
