Answer:
70%
Step-by-step explanation:
210 of 300 is only saying 210/300.
Let's take for example, you wrote an exam where you scored 210 of which the total score Mark is 300. If someone is to tell your score in relation to the total school without using percentage, then the person can simply say, you scored 210 of 300.
210 of 300 = 210/300 * 100/1 = 70%
