Answer 2

The largest bracelet in the chart is 3 3/4 inches. Since she is going to double the length, we need to multiply 3 3/4 inches by 2.

\[3\frac{ 3 }{ 4 }*2\]

Change the mixed number to an improper fraction. Multiple the bottom number times the whole number and then add it to the top number. Keep the bottom number the same.

\[3*4=12\]\[3+12=15\]\[\frac{ 15 }{ 4 }\]Now multiply the improper fraction by 2. \[\frac{ 15 }{ 4 }*2=\]Change 2 to a fraction.\[\frac{ 15 }{ 4 }*\frac{ 2 }{ 1 }=\frac{ 15*2 }{ 4*1 }\]\[\frac{ 30 }{ 4 }\]Change improper fraction 30/4 to a mixed number by dividing the bottom number into the top number.\[7\frac{ 2 }{ 4 }\]Reduce the fraction 2/4
\[7\frac{ 1 }{ 2 }inches\]
