Which of these percentages is closest in value to

lana [24]

$\frac{7}{9} = 0.777777777777777...$

To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.

$0.78*100 = 78$

This shows your answer is (c) 78%.
