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 1.2, 5.5, 3.3, 6.9, 7.7
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	Comparing the leftmost digit, we can see that 7.7 has the highest digit among all five numbers.
6	Step	If the decimal places are the same, continue comparing digits to the right.
7	Step	Among 1.2, 5.5, 3.3, and 6.9, 6.9 has the highest digit.
8	Step	Finally, we compare the whole number before the decimal point. 5.5 has a higher digit than 1.2 and 3.3.
9	Step	Therefore, arranging these numbers in descending order gives us: 7.7, 6.9, 5.5, 3.3, and 1.2.
10	Sumup	Can you summarize what you’ve understood in the above steps?
11	Choice.A	This is the correct choice as it correctly arranges the numbers in descending order	7.7, 6.9, 5.5, 3.3, 1.2
12	Choice.B	This option is incorrect because it does not maintain the descending order of the numbers	7.7, 5.5, 3.3, 1.2
13	Choice.C	This option is incorrect because it places 6.9 before 5.5, which violates the descending order	7.7, 6.9, 5.5, 1.2
14	Choice.D	This option is incorrect because it omits the number 1.2, and it does not maintain the correct descending order	7.7, 6.9, 3.3
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
1.2, 5.5, 3.3, 6.9, 7.7

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

Comparing the leftmost digit, we can see that 7.7 has the highest digit among all five numbers.

Step

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

Step

Among 1.2, 5.5, 3.3, and 6.9, 6.9 has the highest digit.

Step

Finally, we compare the whole number before the decimal point. 5.5 has a higher digit than 1.2 and 3.3.

Step

Therefore, arranging these numbers in descending order gives us: 7.7, 6.9, 5.5, 3.3, and 1.2.

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

This is the correct choice as it correctly arranges the numbers in descending order

7.7, 6.9, 5.5, 3.3, 1.2

Choice.B

This option is incorrect because it does not maintain the descending order of the numbers

7.7, 5.5, 3.3, 1.2

Choice.C

This option is incorrect because it places 6.9 before 5.5, which violates the descending order

7.7, 6.9, 5.5, 1.2

Choice.D

This option is incorrect because it omits the number 1.2, and it does not maintain the correct descending order

7.7, 6.9, 3.3
