1 A toy manufacturer estimates that $6 \%$ of its products are defective. If 550 toys are produced in one day, how many will be defective?

Step 1 ：Convert the percentage to a decimal by dividing the percentage by 100. So, 6% becomes \(\frac{6}{100} = 0.06\).

Step 2 ：Multiply the total number of toys produced in one day (550) by the decimal equivalent of the percentage (0.06). So, the calculation is \(550 \times 0.06 = 33\).

Step 3 ：\(\boxed{33}\) toys are estimated to be defective.
