You paint 1/2 wall in 1/4 hour. At that rate, how long will it take you to paint one wall?
How do you figure out these problems, I seem to have a hard time.
What do you multiply by 1/2 to get 1?
Multiply 1/4 by the same number to find how long it will take to paint one wall.
Thank you Ms. Sue, got it correct.
You're welcome. :-)
To figure out this problem, you need to use the concept of proportions.
Let's break down the given information:
- You paint 1/2 wall in 1/4 hour, which means you can paint 1 wall in X hours.
To find out how long it will take you to paint one wall, you can set up a proportion by equating the ratios of wall painted to the time taken for both scenarios.
The proportion would look like this:
(1/2 wall) : (1/4 hour) = 1 wall : X hours
To solve this proportion, you can cross-multiply:
(1/2) * X = (1/4) * 1
Multiplying across gives:
X/2 = 1/4
To isolate X, you can multiply both sides by 2:
2 * (X/2) = 2 * (1/4)
This simplifies to:
X = 1/2
So, it will take you 1/2 hour to paint one wall.
To summarize the steps:
1. Set up a proportion using the given information.
2. Cross-multiply to eliminate the denominators.
3. Solve for the unknown variable.
4. Simplify the equation, if necessary.
5. Find the value of the unknown variable, which gives you the answer to the problem.
