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 48.5, 46.9, 52.6, 53.9
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, 53.9 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 48.5, 46.9, and 52.6, 52.6 has the highest digit.
8	Step	Finally, we compare the whole number before the decimal point. 48.5 has a higher digit than 46.9.
9	Step	Therefore, arranging these numbers in descending order gives us: 53.9, 52.6, 48.5, and 46.9.
10	Sumup	Can you summarize what you’ve understood in the above steps?
11	Choice.A	Incorrect. The numbers are not in descending order	48.5,46.9,52.6,53.9
12	Choice.B	This is the correct answer, as it arranges the numbers in the correct descending order	53.6,52.6,48.5,46.9
13	Choice.C	Incorrect. The numbers are not in descending order	53.6,48.6,52.5,46.9
14	Choice.D	Incorrect. The order of 52.9 and 49.6 is incorrect, and the rest is also not in descending order	48.5,52.9,49.6,53.9
15	Answer	Option	B
16	Sumup	Can you summarize what you’ve understood in the above steps?

Problem

Rearrange numbers in the descending order
48.5, 46.9, 52.6, 53.9

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, 53.9 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 48.5, 46.9, and 52.6, 52.6 has the highest digit.

Step

Finally, we compare the whole number before the decimal point. 48.5 has a higher digit than 46.9.

Step

Therefore, arranging these numbers in descending order gives us: 53.9, 52.6, 48.5, and 46.9.

Sumup

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

Choice.A

Incorrect. The numbers are not in descending order

48.5,46.9,52.6,53.9

Choice.B

This is the correct answer, as it arranges the numbers in the correct descending order

53.6,52.6,48.5,46.9

Choice.C

Incorrect. The numbers are not in descending order

53.6,48.6,52.5,46.9

Choice.D

Incorrect. The order of 52.9 and 49.6 is incorrect, and the rest is also not in descending order

48.5,52.9,49.6,53.9
