EXAMPLE 5.30

Solution

Divide 43 by 22.



Notice that the differences of 120 and 100 repeat, so there is a repeat in the digits of the quotient; 54 will repeat endlessly. The first decimal place in the quotient, 9, is not part of the pattern. So,

\frac{43}{22}=1.9 \overline{54}


TRY IT 5.59

2 . \overline{45}


TRY IT 5.60

2.3 \overline{18}
