Solving Division Equations Involving Decimals

The video tutorial explains how Francis used a leftover piece of ribbon to make bracelets, each requiring 5/10 foot of ribbon. She made 6 bracelets, and the tutorial demonstrates how to calculate the original length of the ribbon using a division equation. The process involves setting up the equation, isolating the variable by multiplying both sides, and solving to find that the original ribbon was 3 feet long. The lesson focuses on solving one-step division equations involving decimals.

If each bracelet requires 5/10 foot of ribbon, how many feet of ribbon are needed for 6 bracelets?

• 4 feet

• 2 feet

• 3 feet

• 3.5 feet

What is the first step in solving the equation X / 5/10 = 6?

• Add 5/10 to both sides

• Subtract 5/10 from both sides

• Multiply both sides by 5/10

• Divide both sides by 6

What operation is used to isolate the variable X in the equation X / 5/10 = 6?

• Multiplication

• Subtraction

• Division

• Addition

What is the original length of the ribbon if Francis made 6 bracelets?

• 4 feet

• 3 feet

• 5 feet

• 2 feet
