Final answer:
The simplified ratio of non-defective computers to the total number of computers in a shop with 60 units (25 defective) is 7 to 12.
Step-by-step explanation:
The question asks us to find the ratio of non-defective computer units to the total number of computer units in a computer shop. There are 60 computer units in total, and 25 are defective. To find the number of non-defective units, we subtract the defective units from the total:
Non-defective units = Total units - Defective units = 60 - 25 = 35
Now, to find the ratio of non-defective to total units, we write this as a fraction:
Ratio of non-defective to total = Non-defective units / Total units = 35 / 60
This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 5:
Simplified ratio = (35 / 5) / (60 / 5) = 7 / 12
The simplified ratio of non-defective computers to the total number of computers is therefore 7 to 12.
