A fifth-grade student in a primary school is doing exercises in the playground. There are 16 or 12 people in each row, which is exactly the whole row. It is known that there are 140 to 160 fifth graders. May I ask how many people are there in the fifth grade?
某小学五年级同学在操场做操，每行16人或12人，正好是整行．已知五年级同学在140～160人之间．请问五年级一共有多少人？
