Final answer:
The reduced ratio of non-Apple phones to Apple phones is 13:12, calculated by finding the greatest common divisor of the number of non-Apple phones (52) and the number of Apple phones (48) in the box.
Step-by-step explanation:
The question asks us to find the reduced ratio of non-Apple phones to Apple phones in a box containing 100 phones, 48 of which are Apple phones. To answer this, we first determine the number of non-Apple phones, which is 100 - 48 = 52.
Now, we have 52 non-Apple phones and 48 Apple phones. The ratio of non-Apple phones to Apple phones is 52:48. To reduce this ratio, we need to find the greatest common divisor (GCD) of 52 and 48, which is 4. Dividing both numbers by 4 gives us the reduced ratio of 13:12, where 13 represents non-Apple phones and 12 represents Apple phones.
