Exercise 3 Page 62

Divide the numerator by the denominator.

- 0.27

Practice makes perfect

We want to write the given fraction as a decimal number. - 3/11Let's ignore the negative sign for just a moment. Recall that 3 11 means 3÷ 11. Therefore, we will divide the numerator by the denominator. Let's do it!

$3 \div 11$

We can see that the pattern starts to repeat itself after a few steps. This means that the decimal is a repeating decimal. We can write it using bar notation. Remember, the bar goes over the decimal part that repeats itself. 0.272727... = 0.27 Therefore, - 311 written as a decimal is - 0.27.
