I cannot get my brain around questions like this:
1/4 divided by 2/5 = 2/4 x ?
I have 4 problems like this and even the example doesn't make sense - I may have copied it wrong off of the board.
Can anyone help?
Thank you!
You invert the second fraction and then just multiply.
1/4 divided by 2/5 = 1/4 multiplied by 5/2
What do you get?

Click on Dividing Fractions and then on the first link in that section.

OK - I GOT 10/8THS OR REDUCED I GET 1 1/4. IS THAT RIGHT?
NOW I JUST WANT TO LEARN WHY I INVERT THE 2ND FRACTION.
THANK YOU SO MUCH!
There are really only two basic operations in arithmetic, addition and multiplication.
subtraction is just the inverse operation of addition.
e.g. 12 + 5=17
17 - 5 = 17 + (-5)=12
so to subtract we simply add the opposite
likewise, division is the inverse operation to multiplication
eg. 12 x 4 = 48
and 48 ÷ 4 = 12
but 48 x 1/4 = 12
take 1/4 of $48 and you would get $12
divide $48 by 4 and you would get $12

How did you get 10/8?
1/4 divided by 2/5 = 1/4 multiplied by 5/2
When you multiply 1 x 5, you should get 5.
When you multiply 4 x 2, you should get 8.
5/8 is the answer.

how do you concentrate
I need help in log divided
how do you do metric measurement
I need help on how to use an equation to graph?
Here is an example from the text book.
y=x-4
example shows x= -2 -1 1 2
y= -6 -5 -3 -2
I want know how did they show this relationship.
I am having problems with writing fractions. For example, four and fifty-six hundredths. How can I write this as a fraction? Please respond.
To concentrate better, here are some strategies you can try:
1. Eliminate distractions: Find a quiet and clutter-free environment where you can focus without being interrupted. Turn off your phone or put it on silent mode and close any unnecessary tabs or applications on your computer.
2. Set goals and priorities: Clearly define what you want to accomplish and break it down into smaller, manageable tasks. Prioritize your tasks based on importance and urgency to stay organized and focused.
3. Time management: Allocate specific blocks of time for focused work and take regular breaks to avoid mental fatigue. Use techniques like the Pomodoro Technique (working for 25 minutes and then taking a 5-minute break) to enhance productivity.
4. Practice mindfulness: Mindfulness exercises, such as deep breathing or meditation, can help calm your mind and improve your ability to concentrate. Take a few moments to clear your thoughts and center yourself before starting a task.
5. Stay organized: Keep your workspace tidy and organized so that you can easily find what you need. Use tools like to-do lists, calendars, or digital productivity apps to keep track of tasks and deadlines.
6. Stay physically and mentally healthy: Getting enough sleep, eating nutritious meals, and exercising regularly can significantly impact your ability to concentrate. Taking care of your physical and mental well-being will enhance your overall cognitive function.
7. Break tasks into smaller steps: If you find yourself struggling to concentrate because a task feels overwhelming, break it down into smaller, more manageable steps. This will make it easier to focus on one step at a time and reduce feelings of overwhelm.
Remember, concentration is a skill that can be improved with practice. Experiment with different strategies to find what works best for you.
