Calculating Volume with Fractions

The video tutorial explains how to calculate volume using fractions, emphasizing that the process is similar to using whole numbers. It involves multiplying the length, width, and height, applying fraction multiplication rules. The example given is 5/3 times 3/2 times 4/5, which simplifies to a whole number, 2 cm³, after reducing the fraction.

What is the main similarity between calculating volume with fractions and with whole numbers?

• Both use the same formula: length times width times height.

• Both involve dividing the measurements.

• Both require converting to decimals first.

• Both require adding the measurements.

When calculating volume with fractions, what additional rule must be applied?

• Subtracting fractions rule.

• Adding fractions rule.

• Multiplying fractions rule.

• Dividing fractions rule.

Which of the following is the correct formula for volume?
