Rewrite as a simplified fraction.
2.31 with the 1 repeating

Step-by-step explanation:

Let x be equal to that.

Multiply by 1 followed by as many zeros as repeating numbers. In this case it's just one repeating decimal, therefore, 1 followed by 1 zero or 10.

This basically moves the decimal point one number to the right.

Subtract the first equation from this new equation.

--------------------------

The repeating decimal is eliminated and we are left with:

23.1

- 2.3

---------

20.8

We also have 10 - 1 = 9. We are left with:

Divide by 9.

To get rid of the decimal, multiply by 1 followed by as many zeros as decimals. In this case 1.

Let's simplify.

208/2=104

90/2=45
