Final answer:
To find a fraction with a numerator and denominator greater than 300 that can be simplified by dividing both 9 and 8, look for common factors. For example, 360/400 can be simplified to 9/10.
Step-by-step explanation:
To find a fraction with a numerator and denominator greater than 300 that can be simplified by dividing both 9 and 8, we need to look for common factors of 9 and 8.
The common factor between 9 and 8 is 1. So, any fraction with a numerator and denominator greater than 300 that is divisible by both 9 and 8 can be simplified. For example, if we take the fraction 360/400, both 9 and 8 divide evenly into it. The simplified form of this fraction would be 9/10.
