F. 1 1/3 chapters / 1 hour <<
Check my answers please and thank you
B, D, E? are these correct?
Check C and F. One is wrong.
the answers are B D and C are these correct
To find the ratio obtained by scaling up the ratio 5/6 chapters in 1/3 hours, you need to multiply the numerator and denominator of the ratio by the same value.
In this case, we want to scale up the ratio to get a larger number of chapters in a larger number of hours. To achieve this, we can multiply both the numerator and denominator by the same value, such as 3.
When we multiply 5/6 chapters by 3/3 hours (which is equivalent to 1), we get:
(5/6) * (3/3) = 15/18 chapters in 3/3 hours
Simplifying the ratio, we get:
15/18 chapters in 3/3 hours
To further scale up the ratio to 1 hour, we divide both the numerator and denominator by 3/3:
(15/18) / (3/3) = 15/18 chapters in 1 hour
Now let's compare this result to the answer choices:
A. 5 chapters / 18 hours
B. 1 chapter / 2/5 hours
C. 2 1/2 chapters / 1 hour
D. 15 chapters / 6 hours
E. 6 chapters / 15 hours
F. 1 1/3 chapters / 1 hour
The correct answer would be option D, 15 chapters / 6 hours, as it matches the scaled-up ratio we calculated.
Why did you change both C and F?
I think you're guessing.
