Exercise 1 Page 671

To write the given number as a percent, let's first consider the form of the given number.

\frac{5}{6}

We will start by converting the given fraction into the decimal form. To do so, we will rewrite the fraction as a division.

\frac{5}{6} = 5 \div 6

Next, let's use a calculator.

We found the decimal form of

\frac{5}{6} .

\frac{5}{6} = 0.833333 \dots = 0.8 \overline{3}

To convert the decimal into a percent, we need to multiply the decimal by

100

and add a percent sign. When multiplying a decimal by

100,

we can think of this as moving the decimal point two digits to the right.

Multiply By 100 Add the Percent Sign \Rightarrow 0.8 \overline{3} \times 100 = 83 . \overline{3} \Rightarrow 83 . \overline{3} %
