Answer 1

Step 1

Given; Kelly bought a cup of coffee and drank 5/8 of it. Write an addition equation to represent how much coffee is remaining.

Step 2

`\begin{gathered} The\text{ total fraction representing the cup=1} \\ Let\text{ the fraction left be x} \\ Thus; \\ x+(5)/(8)=1 \end{gathered}`

The addition equation representing how much coffee is remaining is;

`\begin{gathered} x=1+(-(5)/(8)) \\ x=(3)/(8) \\ Thus \\ 1+(-(5)/(8))=(3)/(8) \\ \end{gathered}`

Answer;

`1+(-(5)/(8))=(3)/(8)`
