Understanding Division of Fractions

The video tutorial explains how to solve the division of fractions problem: 2/3 divided by 5. It begins with a visual representation of two-thirds using a square divided into three equal parts. The tutorial then demonstrates dividing these two-thirds into five equal sections, leading to the concept of fifteenths. The video further explains that dividing by a number is equivalent to multiplying by its reciprocal, using the example of 2/3 divided by 5 as 2/3 multiplied by 1/5, resulting in 2/15. The tutorial emphasizes understanding the conceptual basis of these operations.

What is the initial problem discussed in the video?

• Subtracting five from two-thirds

• Adding two-thirds and five

• Dividing two-thirds by five

• Multiplying two-thirds by five
