A painter used 1 1/2 gallons of paint to paint 3/4 of a room. At this same rate, how many gallons will it take to paint the whole room?
Sorry for the late reply, but i think he would nees 2/3 gallons
1/2 gollons for 3/4 of the room
This means (1/2 * 1/3) gallons for 1/4 of the room. Because one third of the room already painted would require one third of the paint already used. So,1/4 th of the room requires 1/6 of the paint. So 4/4 would require (4 * 1/6) which is equal to 2/3.
need help please
To find out how many gallons of paint it will take to paint the whole room, we need to determine the fraction of the room that has been painted and then calculate how many gallons of paint that fraction represents.
Given that the painter used 1 1/2 (or 3/2) gallons of paint to paint 3/4 of the room, we can set up a proportion:
3/4 room painted = 3/2 gallons
To find out how many gallons of paint are needed for the whole room, we can set up a proportion using the given information:
1 full room painted = ? gallons (unknown)
Now, we can set up the proportion:
3/4 room painted / 1 = 3/2 gallons / ?
To solve for the unknown value, we can cross-multiply:
(3/4) * ? = (3/2) * 1
Simplifying the equation:
(3/4) * ? = 3/2
To isolate the unknown value, we can multiply both sides of the equation by the reciprocal of (3/4) (which is 4/3):
(3/4) * ? * (4/3) = (3/2) * (4/3)
This simplifies to:
? = 2
Therefore, it will take 2 gallons of paint to paint the whole room.

Do this problem the same way I showed you for your last one. Set up a proportion. Cross multiply and solve for x.
