Converting Lengths and Fractions

The video tutorial explains how to calculate the total length of cables in feet. It starts by introducing the problem of converting different cable lengths from inches and feet to a total length in feet. The tutorial then demonstrates the conversion of 23 inches and 49 inches to feet using mathematical operations. It also shows how to express 8 feet as an improper fraction. Finally, the video adds all the converted lengths to find the total cable length, which is 14 feet.

What is the first step in solving the problem of finding the total cable length in feet?

• Add all the lengths directly.

• Multiply all lengths by 12.

• Convert all lengths to inches.
