How to multiply two rational numbers.

The video tutorial explains how to multiply two rational numbers, 4/5 and 2/3, using a visual method. It involves drawing rectangles to represent each fraction, shading the appropriate parts, and then overlaying the rectangles to find the common shaded area. The result of the multiplication is 8/15.

What are the two rational numbers we need to multiply in this lesson?

• 3/4 and 5/6

• 4/5 and 2/3

• 1/2 and 3/5

• 2/3 and 3/4

How is the rational number 4/5 represented visually?

• A rectangle divided into five parts, with four shaded

• A circle divided into five parts, with four shaded

• A rectangle divided into four parts, with three shaded

• A square divided into five parts, with two shaded

How is the rational number 2/3 represented visually?

• A rectangle divided into two parts, with one shaded

• A circle divided into three parts, with one shaded

• A square divided into three parts, with two shaded

• A rectangle divided into three parts, with two shaded

What is the result of multiplying 4/5 by 2/3?

• 10/15

• 12/15

• 8/15

• 6/15

What do the common shaded parts represent when the two rectangles are combined?

• The difference between the two rational numbers

• The sum of the two rational numbers

• The product of the two rational numbers

• The quotient of the two rational numbers
