Answer:
12/9 or 1-1/3
Step-by-step explanation:
Let X equal the decimal number
Equation 1:
X=1.3¯¯¯(1)
With 1 digits in the repeating decimal group,
create a second equation by multiplying
both sides by 101 = 10
Equation 2:
10X=13.3¯¯¯(2)
Subtract equation (1) from equation (2)
10XX9X===13.3...1.3...12
We get
9X=12
Solve for X
X=129
