Answer:

[tex]3\tfrac{1}{2}[/tex]

Step-by-step explanation:

Given:

Each day M.r Cole used can of paint = [tex]\frac{1}{2}[/tex]

Total number of days he used can of paint = 7

Questioned asked:

How much paint Mr. Cole used after 7 days?

Solution:

By applying unitary method:

M.r Cole used can of paint in one day = [tex]\frac{1}{2}[/tex]

M.r Cole used can of paint in 7 days = [tex]\frac{1}{2} \times7[/tex]

                                                             = [tex]\frac{7}{2}[/tex]

                                                             = [tex]3\tfrac{1}{2}[/tex]

Therefore, M.r Cole used [tex]3\tfrac{1}{2}[/tex] can after 7 days.
