## TL;DR

The video explains how to interpret decimal values and perform operations involving tenths and hundredths.

## Key Insights

• ➗ Shaded areas in diagrams can represent both tenths and wholes, depending on the divisions.
• 🫥 Understanding the number line and its divisions into tenths helps determine decimal values accurately.
• ❓ The relationship between tenths and wholes is crucial in converting fractions and identifying decimal representations.

## Transcript

We're told that "Each square below represents one whole." So this big square right over here is a whole, and then this big square over here is another whole. Then they ask us "Which of the following does the shaded area represent? Select all that apply." So let's see-- the shaded area. We're shaded in blue. So let's see-- one way to think about it ...

### Q: How can you determine the shaded area in a diagram divided into tenths?

The shaded area represents 1 and 1 tenth. This can also be viewed as 11 tenths since all tenths are shaded.

### Q: How do you locate a point on a number line divided into tenths and convert it into decimal form?

Counting the tenths along the number line helps determine the decimal value. For example, 1 and 8 tenths would be written as 1.8.

### Q: How do you write a decimal equivalent to a given number of tenths?

To convert tenths to a decimal, divide the number of tenths by 10. For example, 24 tenths would be written as 2.4.

### Q: What is the decimal representation of 102 hundredths?

102 hundredths is equal to 1.02, as 100 hundredths is equivalent to 1 and 2 hundredths is written as 0.02.
