Answer:
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
