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

Solution

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

Choice-A

This is incorrect because it’s in ascending order, not descending

Wrong 48.5,46.9,52.6,53.9

12

Choice-B

This is correct because the numbers are ordered from largest to smallest

Correct 53.6,52.6,48.5,46.9

13

Choice-C

This is incorrect because the numbers don’t match the original set and aren’t in descending order

Wrong 53.6,48.6,52.5,46.9

14

Choice-D

This is also incorrect because it mixes up the numbers and is not in descending order

Wrong 48.5,52.9,49.6,53.9
