vanessa buys a strip pf 25 postage stamps. The strip of stamps is 21 7/8 inches long. How long is a strip after one stamp is used.
21.875 / 25 = 0.875
21.875 - 0.875 = 21 inches

To find the length of the strip after one stamp is used, we need to subtract the length of one stamp from the total length of the strip.
Given that the strip of stamps is 21 7/8 inches long and there are 25 stamps in the strip, we need to calculate the length of one stamp.
To calculate the length of one stamp, we can divide the total length of the strip by the number of stamps:
Length of one stamp = Total length of the strip / Number of stamps
Length of one stamp = 21 7/8 inches / 25
Now we need to convert the fraction 7/8 into decimal format. Since there are 8 equal parts in one whole, we divide 7 by 8:
7 / 8 = 0.875
Now we can substitute this decimal value back into the equation:
Length of one stamp = 21 + 0.875 inches / 25
Now we can calculate the length of one stamp:
Length of one stamp = 0.875 inches / 25 = 0.035 inches
Since we have the length of one stamp, we can subtract it from the total length of the strip to find the length after one stamp is used:
Length after one stamp is used = Total length of the strip - Length of one stamp
Length after one stamp is used = 21.875 inches - 0.035 inches
Length after one stamp is used = 21.84 inches
Therefore, the strip will be approximately 21.84 inches long after one stamp is used.
