32 1/2 divided by 1/5...

First, convert the mixed number, 32 1/2, to an improper fraction (multiply the whole number and the denominator, then add that to the numerator. In this case, 32 1/2 becomes 65/2. This gets you an equation of 65/2 / 1/5.

Next, use "keep, change, flip."

Keep 65/2.

Change the division sign into a multiplication sign.

Flip 1/5 to 5/1.

You now have 65/2*5/1.

From here, just multiply the numerators together to get your new numerator, and the same but for your denominators.

65*5=325

2*1=2

This gets you 325/2. Simplify, and you get 162.5.

In conclusion, 32.5 divided by 1/5 is equal to 162.5, or 162 1/2.

Okay, let's divide this problem up.

2x+5>10

Subtract 5 from both sides...

2x>5

Divide by 2 on each side...

x>2.5

This means that we know that x is greater than 2.5. Next, let's do 5x-4<20.

5x-4<20

Add 4 to each side...

5x<24

Divide by 5 on each side...

x<4.8

This means that x is less than 4.8.

Now we know that x is greater than 2.5, but less than 4.8.

2.5<x<4.8.

In conclusion, x can be any number from 2.5 to 4.8.

Good job, Guest!

63 days divided by 7 days a week equals 9 weeks.

True, but whenever you are adding two negatives together, you can just subtract the absolute value of the second number from the first.

-10+(-30) turns into -10-30. The answer is -40, as Steven434 said. You can access the calculator on this website by clicking on the home tab at the top of the page.

If you mean 1/7(6207/5400), then you can just multiply the numerators to get your new numerator, and  multiply the denominators to get your new denominators. 1*6207=6207, and 7*5400=37800. Your answer is 6207/37800.

What you can also do is cross multiply.

40/100=x/130

Multiply each numerator by the opposite denominator...

100x=5200

Simplify...

x=52

There you have it! You can also do what the Guest did by multiplying by .40 because it equals 40%.

No operation when a number is next to parentheses just means that you should multiply.

6*(/6x)

There you go!

Let me show you in an example.

First, take the denominator and see how many times it goes in the numerator.

Ex. 13/5

5 goes into 13 2 times.

Then, take that number (in this case 2) and make it your whole number.

Ex. 2 13/5

Finally, multiply the denominator by the number of times it fits into the numerator...

Ex. 5*2=10

...and subtract that from the numerator!

Ex.

13-10=3

Finish it off by putting it together!

Ex. 2 3/5

That's great, Hayley!

Let me show you her work...

72/514=approximately 0.14007

0.14007*100=14.007

If you round, you get 14.

Okay, let's do this step by step.

First, find the LCD of each.

4/5: 5, 10, 15, 20, 25, 30, 35, 49, 45

2/9: 9, 18, 27, 36, 45

It's 45! 45 is your new denominator.

Multiply the numerator of each fraction by the first denominator of the other.

4*9=36

2*5=10

This is the new numerator. So...

36/45+10/45=a

I think you should be able to figure out the rest.
