Answer:
Yes, Owen have enough oil to make the pancakes.
Step-by-step explanation:
Given:
A pancake recipe calls for 1/7 cup of oil per cup of mix.
Owen wants to use 3 1/2 cups of pancake mix. He has 1/2 cup of oil.
Now, to find whether Owen have enough oil to make the pancakes.
So, we use unitary method to solve:
If, [tex]\frac{1}{7}[/tex] cup of oil is used to make pancake = 1.
So, 1 cup of oil is used to make pancakes [tex]=\frac{1}{\frac{1}{7}} = 7.[/tex]
Thus, [tex]\frac{1}{2}[/tex] cup of oil is used to make pancakes = [tex]7\times \frac{1}{2}[/tex]
[tex]=\frac{7}{2} \\\\=3\frac{1}{2} .[/tex]
Hence, Yes, Owen have enough oil to make the pancakes.
