Convert .45 repeated to a rational simplest form

To convert .45 repeating to a rational simplest form, let's call the repeating decimal x.

Since .45 is equivalent to 45/100, we can write:

x = 45/100 + x/100

Multiplying both sides by 100 to eliminate the decimal:

100x = 45 + x

Subtracting x from both sides:

99x = 45

Dividing both sides by 99:

x = 45/99

Thus, .45 repeating can be written in rational simplest form as 45/99.

To convert .45 repeated (or .454545...) to a rational simplest form, we can follow the steps below:

Step 1: Let x = .454545...
Step 2: Multiply x by 100 to move the decimal two places to the right: 100x = 45.454545...
Step 3: Subtract x from 100x: 100x - x = 45.454545... - .454545...
This simplifies to: 99x = 45
Step 4: Divide both sides of the equation by 99: 99x / 99 = 45 / 99
This simplifies to: x = 45/99

Therefore, the rational simplest form of .45 repeated is 45/99.

To convert the decimal number .45 repeated to a rational simplest form, we can set it up as a fraction.

Let's assume x = .45 repeated.

We can multiply both sides of the equation by 100 to shift the decimal point two places:

100x = 45.45 repeated

To eliminate the repeated decimal, we subtract x from both sides:

100x - x = 45.45 repeated - x

99x = 45

Now, we can divide both sides of the equation by 99:

99x / 99 = 45 / 99

Simplifying the fraction gives:

x = 5 / 11

So, .45 repeated in rational simplest form is 5/11.
