Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Answer to Problem 42E

The number as the ratio of two integers is: 0.7¯=79 .

Explanation of Solution

Given information:

Given expression is: 0.7¯=0.77777….

Calculation:

The given number is 0.7¯=0.77777…. The sum of the infinite geometric series whose ratio is <1,S=a1−r

Where, a is initial term and r is the common ratio. We can also write as, 0.7¯=0.77777….=0.7+0.07+0.007+0.0007+….. 0.7¯=710+7102+7103+7104+…….

It is a geometric progression with initial term is 0.7 and common ratio is equal to 110 Therefore, sum of the series is:

  S=0.7(1−110)=79⇒0.7¯=79

The number as the ratio of two integers.is: 0.7¯=79
