4/9 + 1/3

find the least common denominator (LCD) which is 9.

4/9 + 1 × 3/ 3 × 3     makes the denominators the same as the LCD.

4/9 + 3/9       simplify and both denominators are the same.

7/9

What is the check digit, d, for the UPC bar code number shown below? 0-24679-36163-d
Juli2301 [7.4K]

Answer:

The check digit is 7.

Step-by-step explanation:

Check digit can be calculated by the following way:

  • Add all the digits except the check digit that is the last digit on the   right side.

             Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3

             Total = 47

  •      Add the digits at odd starting from left, double this amount and          finally add it with the total from step 1.

             = 0 + 4 + 7 + 3 + 1 + 3

       Sum =  18

      Doubling the sum = 36

     Adding it with the total from step 1, we get

        Total = 36 + 47

        Total = 83

  •  Subtract the last digit of the total from step 2 with 10, and this will be check digit.

        Check Digit  = 10 - 3

        Check Digit  = 7
