Divide 7 by 5, adding a decimal point and zeroes to the former as needed. The division looks like this: 

The quotient, 1.4, is the decimal equivalent of .

Convert the following decimal to a fraction:

To convert this to a fraction, let's begin by changing the decimal to a percent and putting it over 100.

Now, we just need to simplify our fraction. We can do so by dividing out two two's from the top and bottom.

So, our answer is:

Start by finding how much the painting cost after it was put on sale at  off.

Now, we will need to take  off this already reduced price to find the final sale price of the painting.

Make sure to round to the nearest cent.

The final sale price for the painting is .

Recall the equation to find the amount of simple interest generated:

, where  is the initial investment,  is the rate, and  is time in years.

Start by subtracting his balance after six years by his initial investment to get the amount of interest that was generated.

Now, we know the initial investment and the amount of time for this account, so we can now solve for the rate.

Because rate is always expressed in a percentage, multiply by  to get the rate.

Which of the following decimals is equivalent to the fraction ?

To solve this problem efficiently, first eliminate any unreasonable answers. We are given an improper fraction, so we know that our answer must be grater than one. With this in mind we can eliminate one of our answers.

Next, let's make this fraction a mixed number. To do so, subtract the denominator from the numerator. This will become our new numerator. Because 6 only goes into 9 once, we will put a 1 out in front.

Now, can we simplify 3 6ths? Yes we can.

Now, the fraction one-half is equivalent to 0.5 If you weren't sure on this, you can find this out by dividing 1 by 2:

So, our answer is 

There are two ways you can go about solving this. If you have a calculator, you can simply take the fraction answers and figure out which one matches the decimal we need to convert.

If you don't have a calculator, then we will work with the decimal and convert it into a fraction.

There are many different fractions  can be, but for this problem we will use the easiest one. 

We can assume that this is  out of , with our  on the top and our  on the bottom.

It doesn't look exactly right though, and none of our answers are like that. So let's make  become  by moving its decimal place two back. We need to do the same for , whose decimal place would be right behind the number.

We now moved our decimal place two back to create . This is our right answer as if you put this fraction into your calculator you will get , but also that  out of  is the same as saying  out of .

Our answer is .

You can convert  to the fraction:

After you do this, you then need to simplify. You can divide out of numerator and denominator the value , giving you:

You can begin by converting  into the fraction:

Now, you can begin canceling from the numerator and the denominator. You are looking for factors of . The denominator is only made up of  and  factors (because it is a power of ). The denominator is really merely: . This means that it has a total of four s. That is the same as .  Does the numerator have this many twos?  You can try to figure that out by dividing it by . It does! This gets you the value . Therefore, you will have:

, or
