Video Solution

Solution Steps

00:00 Convert to decimal fraction
00:03 Based on the number of zeros in the denominator, we'll know how many places to move the decimal point to the left:
00:07 There are three zeros in the denominator, so we'll move the decimal point 3 places to the left
00:13 Place the numerator in the appropriate position 3 digits after the decimal point
00:24 Remove the remaining zeros
00:31 And this is the solution to the question

Step-by-Step Solution

To solve this problem, let us follow these steps:

  • Step 1: Understand the given fraction 1001000\frac{100}{1000}.
  • Step 2: Simplify the fraction if possible.
  • Step 3: Convert the simplified fraction into a decimal.

Now, let's dive into the details:

Step 1: We are given 1001000\frac{100}{1000}. This fraction represents 100 divided by 1000.

Step 2: The fraction can be simplified because both the numerator (100) and denominator (1000) have a common factor of 100.
Dividing both by 100 gives:

1001000=110 \frac{100}{1000} = \frac{1}{10}

Step 3: Convert 110\frac{1}{10} into a decimal:

The fraction 110\frac{1}{10} means one-tenth, which can be directly written as the decimal 0.10.1.

There are also other decimal forms which retain the same value such as 0.100.10 and 0.1000.100, which are legitimate representations with different coverage of decimal precision.

Therefore, the decimal representation of 1001000\frac{100}{1000} is 0.1, and among the choices provided, the answer choice representing this is "All answers are correct".
