Answer 1

PROBLEM

Total

16 cheddar cheese

8 mozzarella cheese

Solution

He uses

`\begin{gathered} 5(1)/(2)\text{ of cheddar out of 16} \\ 3(1)/(3)\text{ of mozzarella out of 8} \end{gathered}`
`\begin{gathered} \\ \text{Cheddar left = 16 - 5}(1)/(2)\text{ = 10}(1)/(2) \end{gathered}`
`\text{Mozzarella left = 8 - 3}(1)/(3)\text{ = 4}(2)/(3)`
`\begin{gathered} \\ \text{Total ch}eese\text{ left } \\ = \end{gathered}`

`\begin{gathered} \\ =\text{ 10}(1)/(2)\text{ - 4}(2)/(3) \end{gathered}`
`=\text{ 5}(5)/(6)`
