To convert 4.5 years into months we have to multiply 4.5 by the conversion factor in order to get the time amount from years to months. We can also form a simple proportion to calculate the result:

1 yr → 12 mo

4.5 yr → T(mo)

Solve the above proportion to obtain the time T in months:

T(mo) = 4.5 yr × 12 mo

T(mo) = 54 mo

The final result is:
