The number of new calculators tested was 50 . . . 8 were bad and 42 were good.
The ratio of defective ones to new ones tested is 8:50 or 4:25 or 16% .

You simply put the 2 numbers together to find the answer, which is 8:42.
You want to find the ratio in its simplest form. Therefore, you want to find the lowest common multiple of 8 and 42.
2 goes into both numbers.
8 / 2 = 4.
42 / 2 = 21
The answer is 4:21.
