EXAMPLE 5.30

Divide \(43\) by \(22\).

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,

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


EXAMPLE 5.31

    \(\frac{7}{8}+6.4\)
Change \(\frac{7}{8}\) to a decimal. change 7/8 to a decimal \(0.875+6.4\)
Add.   \(7.275\)
