Title: Identify the types of fraction

Grade: 4-a Lesson: S1-L4

Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	Rearrange numbers in the descending order 22.5, 24.5, 36.5, 38.9
2	Step	In this problem, all numbers have one digit after the decimal point.
3	Hint	When comparing decimals with the same digits after the decimal point, the one with the larger whole number part is larger.
4	Clue	If the whole number parts are also the same, compare the tenths place (the first digit after the decimal point).
5	Step	The largest decimal is the one with the highest digit in the tenths place. In this case, 38.9 has a tenths place digit of 9, which is larger than any other.
6	Step	If the decimal places are the same, continue comparing digits to the right.
7	Step	Among 22.5, 24.5, and 36.5, 36.5 has the highest digit.
8	Step	Finally, we compare the whole number before the decimal point. 24.5 has a higher digit than 22.5.
9	Step	Therefore, arranging these numbers in descending order gives us: 38.9, 36.5, 24.5, and 22.5.
10	Sumup	Can you summarize what you’ve understood in the above steps?
11	Choice.A	Correct, matches the descending order	38.9, 36.5, 24.5, 22.5
12	Choice.B	Incorrect, it’s the original order	22.5, 24.5, 36.5, 38.9
13	Choice.C	Incorrect, the order is not descending	38.9, 24.5, 36.5, 22.5
14	Choice.D	Incorrect, the order is not descending	22.5, 24.5, 38.5, 36.9
15	Answer	Option	A
16	Sumup	Can you summarize what you’ve understood in the above steps?

Answer

Problem

Rearrange numbers in the descending order
22.5, 24.5, 36.5, 38.9

Step

In this problem, all numbers have one digit after the decimal point.

Hint

When comparing decimals with the same digits after the decimal point, the one with the larger whole number part is larger.

Clue

If the whole number parts are also the same, compare the tenths place (the first digit after the decimal point).

Step

The largest decimal is the one with the highest digit in the tenths place. In this case, 38.9 has a tenths place digit of 9, which is larger than any other.

Step

If the decimal places are the same, continue comparing digits to the right.

Step

Among 22.5, 24.5, and 36.5, 36.5 has the highest digit.

Step

Finally, we compare the whole number before the decimal point. 24.5 has a higher digit than 22.5.

Step

Therefore, arranging these numbers in descending order gives us: 38.9, 36.5, 24.5, and 22.5.

Sumup
