Lena can knit 14 square inches of a blanket in 3 1/2 hours. Find the number of square inches knit per hour and the number of hours spent knitting per square inch.
To find the number of square inches knit per hour, divide the number of square inches knit by the number of hours spent knitting: 14 square inches / 3.5 hours = <<14/3.5=4>>4 square inches/hour.
To find the number of hours spent knitting per square inch, divide the number of hours spent knitting by the number of square inches knit: 3.5 hours / 14 square inches = <<3.5/14=0.25>>0.25 hours/square inch. Answer: \boxed{4 \, \text{square inches/hour}} and \boxed{0.25 \, \text{hours/square inch}}.
To find the number of square inches knit per hour, divide the number of square inches knit by the number of hours spent knitting:
Square inches knit per hour = 14 square inches / 3.5 hours
Simplifying the division:
Square inches knit per hour = 4 square inches / 1 hour
Therefore, Lena can knit 4 square inches of a blanket per hour.
To find the number of hours spent knitting per square inch, divide the number of hours spent knitting by the number of square inches knit:
Hours spent knitting per square inch = 3.5 hours / 14 square inches
Simplifying the division:
Hours spent knitting per square inch = 0.25 hours / 1 square inch
Therefore, Lena spends 0.25 hours knitting per square inch.
To find the number of square inches knit per hour, you can divide the number of square inches knit by the number of hours spent knitting.
In this case, Lena can knit 14 square inches of a blanket in 3 1/2 hours. We need to convert the 3 1/2 hours into an improper fraction. 3 1/2 can be written as 7/2.
So, the number of square inches knit per hour can be found by dividing the number of square inches (14) by the number of hours spent knitting (7/2):
14 / (7/2) = 14 * (2/7) = 4 square inches
Therefore, Lena can knit 4 square inches per hour.
To find the number of hours spent knitting per square inch, you can divide the number of hours spent knitting by the number of square inches knit.
In this case, Lena can knit 14 square inches of a blanket in 3 1/2 hours. We need to convert the 3 1/2 hours into an improper fraction. 3 1/2 can be written as 7/2.
So, the number of hours spent knitting per square inch can be found by dividing the number of hours spent knitting (7/2) by the number of square inches knit (14):
(7/2) / 14 = 7/ (2*14) = 7/28 = 1/4 hour
Therefore, Lena spends 1/4 hour (or 15 minutes) per square inch.
