Exercise 26 Page 269

Start by writing the given mixed number as a fraction. Then, divide the numerator by the denominator.

5.3

Practice makes perfect

We want to write the given mixed number as a decimal. 5 13 We will first rewrite it as a fraction.

5 13

▼

Rewrite 5 13 as 16/3

a bc=a* c+b/c

5* 3+1/3

Identity Property of Multiplication

15+1/3

Add terms

16/3

We found that 5 13 is equal to 16 3 when it is written as a fraction. This means that we actually want to find the quotient 16÷ 3. We find the quotient by dividing the numerator of the fraction by its denominator. Let's do it!

We found that 163 written as a decimal is 5.3. Since we previously found that 5 13 is equal to 163, we can say that 5 13 written as a decimal is 5.3. 5 13= 163=5.3
