Chemistry: question about converting pressures? help!?

A gas has a pressure of 1.61 atm and occupies
a volume of 7 L. If the gas is compressed to
a volume of 2.7 L, what will its pressure be,
assuming constant temperature?
Answer in units of atm.

I set up a proportion and got .621 but, this answer was wrong!

Can someone please help me with how to solve this question? (:

PV=nRT. nRT is constant, so P1V1=P2V2

1.61*7=V2*2.7
