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

5.875

Practice makes perfect

We want to write the given mixed number as a decimal. 5 78 We will first rewrite it as a fraction.

5 78

▼

Rewrite 5 78 as 47/8

a bc=a* c+b/c

5* 8+7/8

Identity Property of Multiplication

40+7/8

Add terms

47/8

We found that 5 78 is equal to 47 8 when it is written as a fraction. This means that we actually want to find the quotient 47÷ 8. We find the quotient by dividing the numerator of the fraction by its denominator. Let's do it!

We found that 478 written as a decimal is 5.875. Since we previously found that 5 78 is equal to 478, we can say that 5 78 written as a decimal is 5.875. 5 78= 478=5.875
