Which ratio can you get by scaling up the ratio 5/6 chapters in 1/3 hours
A. 5 chapters / 18 hours<<
B. 1 chapter / 2/5 hours
C. 2 1/2 chapters / 1 hours<<
D. 15 chapters / 6 hours <<
E. 6 chapters / 15 hours
F. 1 1/3 chapters / 1 hour
sorry, B is fine
1chap / 2.5 chap/hr = 10/25 = 2/5 hr
To scale up a ratio, you need to multiply both the numerator and the denominator by the same factor. In this case, we want to scale up the ratio 5/6 chapters in 1/3 hours.
To find the scaling factor, divide the desired denominator by the given denominator: (18 hours) / (1/3 hours) = 18 / (1/3) = 18 * (3/1) = 54.
Now, multiply both the numerator and the denominator of the given ratio by this scaling factor: (5/6) * 54 = (5 * 54) / (6 * 1) = 270 / 6.
Simplify the fraction if possible. In this case, both the numerator and denominator are divisible by 6: 270 / 6 = 45.
So, the scaled up ratio is 45 chapters in 18 hours.
Looking at the answer choices:
A. 5 chapters / 18 hours - This is not the scaled up ratio.
B. 1 chapter / 2/5 hours - This is not the scaled up ratio.
C. 2 1/2 chapters / 1 hour - This is not the scaled up ratio.
D. 15 chapters / 6 hours - This is not the scaled up ratio.
E. 6 chapters / 15 hours - This is not the scaled up ratio.
F. 1 1/3 chapters / 1 hour - This is not the scaled up ratio.
The correct answer is A. 5 chapters / 18 hours.
B. 1 chapter / 2/5 hours
C. 2 1/2 chapters / 1 hours
D. 15 chapters / 6 hours
They all is equal to 5/2 or 2.5
(5/6) / (1/3) = 5/2 chapters/hr = 2.5 hr/chap is right
so yes, C
not A, 5 chap / 2.5 chap/hr = 2 hr
B is 1 chap, obvious no
D is 15 chap /2.5 chap/hr = 150/25 = 6 hr Yes
