In a shipment of 1000 light bulbs 1/40 of the bulbds were defective. What is the ratiio of defective bulbs to nondefective bulbs?

1/40 = x/1000

Solve for x.

Solve for x.

To find the ratio of defective bulbs to non-defective bulbs, we need to know the number of defective bulbs and the number of non-defective bulbs.

Given that 1/40 of the bulbs were defective, we can calculate the number of defective bulbs as follows:

Number of defective bulbs = (1/40) * 1000
Number of defective bulbs = 25

To find the number of non-defective bulbs, we subtract the number of defective bulbs from the total number of bulbs:

Number of non-defective bulbs = 1000 - 25
Number of non-defective bulbs = 975

Therefore, the ratio of defective bulbs to non-defective bulbs is:

Ratio of defective bulbs to non-defective bulbs = 25/975
Ratio of defective bulbs to non-defective bulbs = 1/39

To find the ratio of defective bulbs to non-defective bulbs, we first need to determine the number of defective and non-defective bulbs in the shipment.

Given that 1/40 of the bulbs were defective, we can calculate the number of defective bulbs by multiplying the total number of bulbs by 1/40:
Number of defective bulbs = 1000 * 1/40 = 25

To find the number of non-defective bulbs, we subtract the number of defective bulbs from the total number of bulbs:
Number of non-defective bulbs = 1000 - 25 = 975

Finally, we can state the ratio of defective bulbs to non-defective bulbs as follows:
Ratio of defective bulbs to non-defective bulbs = 25:975

However, we can simplify this ratio by dividing both numbers by their greatest common divisor, which in this case is 25:
Simplified ratio of defective bulbs to non-defective bulbs = 1:39
