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
45.3, 56.3, 55.1, 63.4, 65.2

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 65.2 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 45.3, 56.3, 55.1, and 63.4, 63.4 has the highest digit.

8

Step

Finally, we compare the whole number before the decimal point. 56.3 has a higher digit than 55.1 and 45.3.

9

Step

Therefore, arranging these numbers in descending order gives us: 65.2, 63.4, 56.3, 55.1, and 45.3.
