Answer 2

Answer:

no they are not in proportion.

Step-by-step explanation:

2:3 = 2/3;

4:5 = 4/5;

we know that formula of proportion is-

first term / second term = third term/ fourth term ;

therefore,

                2/3 should be equal to 4/5 if they are in proportion;

but 2/3 is not equal to 4/5;

so, 2:3 and4:5 are not in proportion.
