Stacy is painting her bedroom. She is able to paint 3/4 of the bedroom in 3 hours. At this rate, how long will it take her to
paint the entire room?
A. 12
B. 4 hours
C. 9/4
D. 6 hours
To find the time it will take Stacy to paint the entire room, we need to find the reciprocal of the fraction she can paint in 1 hour.
The fraction she can paint in 1 hour is 3/4. The reciprocal of this fraction is 4/3.
Therefore, it will take Stacy 4/3 hours to paint the entire room.
So the answer is C. 9/4.
What is 3/10 divided by 1/3
To divide fractions, we multiply the first fraction by the reciprocal of the second fraction.
So, 3/10 divided by 1/3 is equal to:
(3/10) * (3/1)
This simplifies to:
(3 * 3) / (10 * 1)
= 9/10
So, 3/10 divided by 1/3 is equal to 9/10.
9/10 divide by 2/3
To divide 9/10 by 2/3, we multiply the first fraction by the reciprocal of the second fraction.
So, 9/10 divided by 2/3 is equal to:
(9/10) * (3/2)
This simplifies to:
(9 * 3) / (10 * 2)
= 27/20
So, 9/10 divided by 2/3 is equal to 27/20.
5/6 divided by 6/7
To divide 5/6 by 6/7, we multiply the first fraction by the reciprocal of the second fraction.
So, 5/6 divided by 6/7 is equal to:
(5/6) * (7/6)
This simplifies to:
(5 * 7) / (6 * 6)
= 35/36
So, 5/6 divided by 6/7 is equal to 35/36.
