Examples with solutions for All Operations in Decimal Fractions: Division by 100

Exercise #1

1036:100= 1036:100=

Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Understand the given information and operation.
  • Step 2: Apply the rule for division by 100.
  • Step 3: Perform the calculation and check against the choices.

Now, let's work through each step:

Step 1: We need to divide 1036 by 100. This is equivalent to finding how many hundreds fit into 1036.

Step 2: When dividing a number by 100, the decimal point is shifted two positions to the left. The original number 1036 can be expressed as 1036.0 (adding a decimal point and a zero for clarity). By moving the decimal point two places to the left, we convert 1036.0 to 10.36.

Step 3: Therefore, 1036÷100=10.36 1036 \div 100 = 10.36 .

Comparing this result to the given multiple-choice options, the correct answer is choice 2, which is 10.36 10.36 .

Therefore, the solution to this problem is 10.36 10.36 .

Answer

10.36 10.36

Exercise #2

9.19:100= 9.19:100=

Video Solution

Step-by-Step Solution

To solve the division of 9.19 9.19 by 100, we follow these steps:

  • Identify the initial position of the decimal point in 9.19 9.19 .
  • Move the decimal point two places to the left since we are dividing by 100.
  • Record the resulting number.

Let's work through this:


Original number: 9.19 9.19

Step 1: Current position of the decimal in 9.19 9.19 is between 9 and 1.

Step 2: Move the decimal two places to the left:

- First move: From between 9 and 1 to before 9, it becomes 0.919 0.919

- Second move: Insert an extra 0 to the left, resulting in 0.0919 0.0919


Therefore, the result of 9.19÷100 9.19 \div 100 is 0.0919\mathbf{0.0919}.

The correct choice matches the calculated result, which confirms choice 2 2 : 0.0919 \mathbf{0.0919} .

Answer

0.0919 0.0919

Exercise #3

118:100= 118:100=

Video Solution

Step-by-Step Solution

To solve this problem, we need to divide 118 118 by 100 100 . To do this, we'll use the method of moving the decimal point.

The number 118 118 can be expressed as 118.0 118.0 with an implied decimal point at the end. When dividing by 100 100 , which is 102 10^2 , we move the decimal point two places to the left to find the quotient.

  • First Place: 118.011.80 118.0 \to 11.80
  • Second Place: 11.801.180 11.80 \to 1.180

After moving the decimal two places to the left, the result becomes 1.18 1.18 .

Therefore, the solution to the problem is 1.18 1.18 .

Answer

1.18 1.18
