Step1: Convert 5 feet 3 inches to feet

1 inch = 1/12 feet, so 3 inches = 3/12 = 0.25 feet. Then 5 feet 3 inches = 5 + 0.25=5.25 feet.

Step2: Divide the total length by the length of each piece

Number of pieces = 32÷5.25=$\frac{32}{\frac{21}{4}}=\frac{128}{21}\approx6.095$. The number of whole - pieces is 6.

Step1: Calculate the number of motors assembled in a week

The team can assemble 4 motors per day and there are 5 working days in a week. So the number of motors assembled in a week is 4×5 = 20 motors.

Step2: Calculate the number of widgets needed

It takes 11 widgets to assemble one motor. So the number of widgets needed for 20 motors is 11×20=220 widgets.

Step1: Convert 4 pounds 12 ounces to pounds

1 ounce = 1/16 pounds, so 12 ounces = 12/16 = 0.75 pounds. Then 4 pounds 12 ounces = 4 + 0.75 = 4.75 pounds.

Step2: Calculate the cost

The corn - meal sells for $1.28 per pound. So the cost of a 4.75 - pound sack is 1.28×4.75 = 1.28×(4 + 0.75)=1.28×4+1.28×0.75 = 5.12+0.96 = 6.08 dollars.
