4 hours
Step-by-step explanation:
In 6 hours, J paints 1 room
So, in 1 hour, J paints 1/6 th of the room
Using similar logic, in 1 hour, T paints 1/12 th of the room.
Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.
1/4 of the room is painted in 1 hour
So, 1 room is painted in 1 1/4=4 hours
30%
1L = 1000ml
--------------------
100%-> 1000
1%-> 10
300 ÷ 10 = 30%
40m Since it is the shortest side
20
To get the answer, you have to find what number 15 is 75 percent of.
