answer should be 2
lets take side KL and side PR, two corresponding sides. 
side KL measures 5 units and side PR measures 10. 
to get from 5 units to 10 units, you multiply the length of side KL by 2, giving the length of side PR.
That is the same for the rest of the sides. Multiply each side of JKLM by 2 to get NPRS.
