Janet has played guitar longer.
EX.
To compare the lengths of time Francois and Janet have played guitar, we need to convert their time periods into a consistent unit. Francois has played for 4 years, which is equivalent to 4 x 12 = 48 months. Janet has played for 32 months.
Comparing the two, Janet has played guitar for 32 months, which is shorter than Francois' 48 months. Therefore, Francois has played guitar longer than Janet.
