Reduction and Expansion of Decimal Fractions: Identify the greater value

Examples with solutions for Reduction and Expansion of Decimal Fractions: Identify the greater value

Exercise #1

Fill in the missing sign:

0.8 — 0.08 0.8\text{ }_{—\text{ }}0.08

Video Solution

Step-by-Step Solution

To compare which is greater, we will compare the numbers by adding 0 to 0.8 as follows:

0.80?0.08 0.80\text{?}0.08

Let's note that before the decimal point, we have 0 in both numbers.

After the decimal point, we have 8 compared to 0.

Since 8 is greater than 0, the appropriate sign is as follows:

0.80 > 0.08

Answer

>

Exercise #2

Fill in the missing sign:

0.008 — 0.08 0.008\text{ }_{—\text{ }}0.08

Video Solution

Step-by-Step Solution

In order to compare which is larger, we'll compare the numbers by adding 0 to 0.08 in the following way:

0.008?0.080 0.008\text{?}0.080

Note that before the decimal point we have 0 in both numbers

After the decimal point in both numbers we have 0

The different numbers are the following ones, 0 versus 8

Since 8 is greater than 0, the appropriate sign is:

0.008 < 0.080

Answer

<

Exercise #3

Fill in the missing sign:

0.3 — 0.30 0.3\text{ }_{—\text{ }}0.30

Video Solution

Step-by-Step Solution

In order to compare which is greater, we will compare the numbers by adding 0 to 0.3 in the following way:

0.30?0.30 0.30\text{?}0.30

Note that before the decimal point we have 0 in both numbers

After the decimal point in both numbers we have the number 3 and then the number 0

Therefore, the appropriate sign is:

0.30=0.30 0.30=0.30

Answer

Exercise #4

Fill in the missing sign:

1.5 — 1.50 1.5\text{ }_{—\text{ }}1.50

Video Solution

Step-by-Step Solution

In order to compare which is larger, we'll compare the numbers by adding 0 to 1.5 as follows:

1.50?1.50 1.50?1.50

Note that before the decimal point we have 1 in both numbers

After the decimal point in both numbers we have 5 and then 0

Therefore the numbers are equal to each other and the appropriate sign is:

1.50=1.50 1.50=1.50

Answer

= =

Exercise #5

Fill in the missing sign:

1.33 — 1.333 1.33\text{ }_{—\text{ }}1.333

Video Solution

Step-by-Step Solution

In order to compare which is larger, we will compare the numbers by adding 0 to 1.33 as follows:

1.330?1.333 1.330\text{?}1.333

Note that before the decimal point we have 1 in both numbers

After the decimal point in both numbers we have the number 3 and then the number 3

The different numbers are the last numbers 0 versus 3

Since 3 is greater than 0 the appropriate sign is:

1.330 < 1.333

Answer

<

Exercise #6

202.1 — 202.01 202.1\text{ }_{—\text{ }}202.01

Video Solution

Step-by-Step Solution

Let's compare the numbers in the following way:

We notice that before the decimal point, both numbers start with 202

After the decimal point, we notice that the number is 1 versus 0

Since 1 is greater than 0, the appropriate sign is:

202.1 > 202.01

Answer

Exercise #8

Fill in the missing sign:

1.500 — 1.50 1.500\text{ }_{—\text{ }}1.50

Step-by-Step Solution

To compare the numbers 1.500 1.500 and 1.50 1.50 , observe the following:

1. 1.500 1.500 and 1.50 1.50 are equivalent because trailing zeros do not change the value of a decimal.

2. Therefore, 1.500=1.50 1.500 = 1.50 .

The correct sign to fill the gap is = = .

Answer

= =

Exercise #9

Fill in the missing sign:

0.45 — 0.450 0.45\text{ }_{—\text{ }}0.450

Step-by-Step Solution

Let's compare the two decimal numbers 0.45 0.45 and 0.450 0.450 .

1. Convert 0.45 0.45 to the same decimal places as 0.450 0.450 :

0.45=0.450 0.45 = 0.450

2. Now compare the expanded forms. Since both are numerically equal, we have:

0.450=0.450 0.450 = 0.450

Therefore, the missing sign is = = .

Answer

= =

Exercise #10

Fill in the missing sign:

2.300 — 2.30 2.300\text{ }_{—\text{ }}2.30

Step-by-Step Solution

To determine the relationship between 2.300 2.300 and 2.30 2.30 , follow these steps:

1. Note that 2.300 2.300 can be simplified to 2.30 2.30 because trailing zeros in a decimal do not affect its value.

2. Therefore, 2.300=2.30 2.300 = 2.30 .

The missing sign is = = .

Answer

= =

Exercise #11

Fill in the missing sign:

0.33 — 0.303 0.33\text{ }_{—\text{ }}0.303

Step-by-Step Solution

To decide whether 0.33 0.33 is less than, greater than, or equal to 0.303 0.303 , align both by the decimal point:

0.33 0.33 can be considered as 0.330 0.330 . Compare the numbers starting from the left:
The digit "3" after the decimal in 0.33 0.33 is greater than "3" in 0.303 0.303 due to the next digit in the sequence, making 0.33 0.33 greater than 0.303 0.303 . Thus, the sign is > > .

Answer

> >

Exercise #12


Fill in the missing sign:

0.305 — 0.30 0.305\text{ }_{—\text{ }}0.30

Video Solution

Step-by-Step Solution

In order to compare which is greater, we will compare the numbers by adding 0 to 0.30 in the following way:

0.305?0.300 0.305\text{?}0.300

Note that before the decimal point we have 0 in both numbers

After the decimal point in both numbers we have the number 3 and then the number 0

The different numbers are the last numbers 5 and 0

Since 5 is greater than 0 the appropriate sign is:

0.305 > 0.300

Answer

Exercise #13

Fill in the missing sign:

0.35 — 0.135 0.35\text{ }_{—\text{ }}0.135

Video Solution

Step-by-Step Solution

To compare which is greater, we'll compare the numbers by adding 0 to 0.35 as follows:

0.350?0.135 0.350\text{?}0.135

We should notice that before the decimal point, we have 0 in both numbers.

After the decimal point, we have 3 compared to 1.

Since 3 is greater than 1, the appropriate sign is:

0.350 > 0.135

Answer

>

Exercise #17

Fill in the missing sign:

66.101 — 6.6101 66.101\text{ }_{—\text{ }}6.6101

Video Solution

Step-by-Step Solution

Let's compare the numbers in the following way:

We notice that before the decimal point, we have the number 66 versus the number 6

Since 66 is greater than 6, the appropriate sign is:

66.101 > 6.6101

Answer

Exercise #18

Fill in the missing sign:

24.305 — 24.315 24.305\text{ }_{—\text{ }}24.315

Video Solution

Step-by-Step Solution

First let's compare the numbers.

We can see that, before the decimal point, both numbers start with 24.

After the decimal point, we also have the digit 3 in both numbers.

Then the digits are 0 in one number and 1 in the other.

Since 1 is greater than 0, the appropriate sign is the 'less-than' sign:

24.305 < 24.315
