Marge cuts 16 pieces.
Each piece has a length of 3/8 inches
she needs to cut 16 pieces of 3/8 inches each
amount of tape needed - [tex] \frac{16}{1}*\frac{3}{8} [/tex]
when mulitplying numbers with fractions, numerators should be multiplied by numerators and denominators by denominators
[tex] \frac{16*3}{1*8} = \frac{48}{8} = 6 [/tex]
amount of tape needed = 6 inches
