56/64 x 100 = 87.5 percent
To get at least 64% you can miss at most 100 - 64 % = 36 % Percent means "out of 100" 36 % of 56 = 36/100 x 56 = 20.16 → Can miss 20 questions.
lets see...lets apply a simple ratio... (56/f) = (64/100) 64(f) = 5600 87.5 = f = your answer O.O
56 + 64 = 120
56-64 simplified = -8
56/64 x 100 = 87.5 percent
To get at least 64% you can miss at most 100 - 64 % = 36 % Percent means "out of 100" 36 % of 56 = 36/100 x 56 = 20.16 → Can miss 20 questions.
The answer is 3.88 (388%)
lets see...lets apply a simple ratio... (56/f) = (64/100) 64(f) = 5600 87.5 = f = your answer O.O
56/64 = 7/8
56
