Marge cut 16 pieces of tape for mounting pictures on poster board. each piece of tape was 3/8 inch long. how much tape did marge use?

Hello!

Let's convert 3/8 to a decimal and then multiply the length of each piece of tape by how many pieces Marge used.

To convert a fraction to a decimal, simply divide its numerator by its denominator:

3 ÷ 8 = 0.375

Next, multiply this by the amount of pieces Marge cut.

0.375 × 16 = 6

Therefore, Marge used 6 inches of tape.
