Final answer:
To determine the number of times cheaper the memory problem is, divide the price of the memory problem by the price of the other item. The memory problem is 0.5 times cheaper than the other item.
Step-by-step explanation:
To determine how many times cheaper the memory problem is, you need to compare the prices of the two items. Let's say the memory problem costs $100 and the other item costs $200.
To find the ratio of their prices, divide the price of the memory problem by the price of the other item:
$100 / $200 = 0.5.
This means that the memory problem is 0.5 times cheaper than the other item. You can also express this as being 50% cheaper.
