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.
