I have two questions.
1) Convert 1.2(with the 2 as a recurring number) into a fraction.
My book instructs to multiply the decimal number by ten if there is only one recurring number so
Then the book instructs me to subtract 0.12 from 1.2 .
Then 9X= 1.08
and the fraction for this decimal is 1.08/9.
Am I correct?
Can someone please help me with this word problem?
