Mastering Cross-Canceling in Fraction Division

The video tutorial explains how to use cross cancelling when dividing fractions. It starts with a problem involving 7/8 divided by 3/4, where initially no cross cancelling seems possible. By flipping the second fraction and preparing to multiply, cross cancelling becomes feasible. The tutorial demonstrates simplifying the problem by cancelling common factors, then multiplying across to get an improper fraction. Finally, it shows how to convert the improper fraction into a mixed number, providing a clear step-by-step guide to solving the problem.

What is the initial problem presented in the video?

• 7/8 / 3/4

• 7/8 * 3/4

• 7/8 + 3/4

• 7/8 - 3/4

Why can't we cross cancel immediately in the given problem?

• The fractions are mixed numbers.

• The fractions are improper.

• The fractions are already simplified.

• There are no common factors between the numerators and denominators.

What is the first step after flipping the second fraction?

• Add the fractions.

• Cross cancel the common factors.

• Simplify the fractions.

• Subtract the fractions.

Which numbers are cross cancelled in the problem?

• 7 and 3

• 4 and 8

• 7 and 4

• 3 and 8

What is the result of multiplying the numerators after cross cancelling?

• 6

• 8

• 7

• 14

How do you convert the improper fraction 7/6 to a mixed number?

• 1 and 3/6

• 1 and 1/6

• 2 and 1/6

• 1 and 2/6
