Question

 In a shipment of airplane parts, 5% are known to be defective. If 23 parts are found to be defective, how many parts are in the shipment?

Answer 1

Hi Jaila!

Since we know that 5% of any shipment of airplane parts is going to be defective, that suggests that in this particular shipment of airplane parts that the 23 parts that were defective was 5% of the total number of parts in the shipment.

Remember that if you knew the total of parts, you would multiply by 5% to get the 23 parts that were defective. Therefore, if you know that 5% of the total is 23 parts, you would divide the 23 parts by 5% to arrive at the total number of parts.

Hope that helps!
