Kelly saved 3/7 of her salary and spent the remaining 4/7 of her salary. May I know what does the words "spent the remaining 4/7 of her salary" mean? Thanks a lot.

Imagine that there are 7 total parts of the salary from that 3 parts are saved and the remaining (7 - 3 = 4) 4 parts of the salary are spent.
