Jenna is hemming her prom dress. The dress's hem is 3 feet long. Each stitch Jenna makes is 1/4 inch long. If Jenna makes 24 stitches per minute, how many minutes does it take Jenna to hem her dress?
First find how many inches the hem is by multiplying the length in feet by the number of inches per foot: 3 feet * 12 inches/foot = <<3*12=36>>36 inches
Then divide the length in inches by the length of each stitch to find how many stitches Jenna makes: 36 inches / .25 inches = <<36/.25=144>>144 stitches
Then divide the number of stitches by Jenna's stitching rate to find how long it takes her: 144 stitches / 24 stitches/minute = <<144/24=6>>6 minutes
