Real problems from the practice worksheets, solved one step at a time.

1. Example 1

   What is 66% of 198?

   1. 66% means 66 out of every 100, so 66% of 198 = 198 × 66 ÷ 100.
   2. Multiply: 198 × 66 = 13068.
   3. Divide by 100: 13068 ÷ 100 = 130.68.
   4. So 66% of 198 is 130.68.

   Answer: 130.68

2. Example 2

   What is 71% of 233?

   1. 71% means 71 out of every 100, so 71% of 233 = 233 × 71 ÷ 100.
   2. Multiply: 233 × 71 = 16543.
   3. Divide by 100: 16543 ÷ 100 = 165.43.
   4. So 71% of 233 is 165.43.

   Answer: 165.43

3. Example 3

   What is 76% of 68?

   1. 76% means 76 out of every 100, so 76% of 68 = 68 × 76 ÷ 100.
   2. Multiply: 68 × 76 = 5168.
   3. Divide by 100: 5168 ÷ 100 = 51.68.
   4. So 76% of 68 is 51.68.

   Answer: 51.68
