Exercise 8 Page 17

To write a fraction as a decimal, divide the numerator by the denominator.

8.44

Practice makes perfect

We want to find the decimal equivalent of 8 49. Before we evaluate the expression, let's first rewrite the expression so that all of the numbers are fractions.

8 49

a bc=a* c+b/c

8* 9+4/9

Multiply

72+4/9

Add terms

76/9

Now, we will write this fraction as a decimal. To do so, we divide the numerator by the denominator.

Applet to compute the division of two numbers

The quotient is a repeating decimal, so we draw a horizontal bar on top of the repeated digits. 8 49 = 8.44
