Thanks, CPhill.

I usually just google what I want a picture of. (In this case, I just googled "number line generator")

Then, if I want to edit the picture at all, I just use a paint program I have on my computer called paint.net

No, -1.4 is less than -0.8.

Although it may seem like -1.4 is bigger than -0.8, we have to remember that these are negative numbers.

Here are the two numbers on a number line:

Here you can see that -1.4 is to the left of -0.8, so it is smaller than it.

I believe we are looking for 10% of 2.000

10% is really .1 as a decimal, because if we had 100% it would be 1.

of means to multiply

So now we have:

.1 x 2.000

which comes out to:

0.2

According to Wikipedia, "Mathematics is the study of topics such as quantity, numbers, structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.^"

To solve this, we just need to divide 7.717 by 95.

You could do this with long division, but I usually just use a calculator when dividing numbers with decimals.

$${\frac{{\mathtt{7.717}}}{{\mathtt{95}}}} = {\mathtt{0.081\: \!231\: \!578\: \!947\: \!368\: \!4}}$$

 Or we can round this up to about 0.08 miles a minute for practical purposes.

We have (0.15)2x100

Since there is no mathematical symbol between the (0.15) and 2, it means to multiply.

0.15*2*100         --- * means multiply in computer language, so as to not confuse it with the algebraic unknown x

.3*100

30

To check this, you can always put the question it in the website's calculator!

No, don't worry about that at all rosala!

I actually like it when people answer after me. If we have multiple people answering and getting the same answer then we know it's right!

Since we are adding a negaive fraction, it is the same thing as just subtracting that fraction.

$${\frac{{\mathtt{3}}}{{\mathtt{5}}}}{\mathtt{\,-\,}}\left({\frac{{\mathtt{4}}}{{\mathtt{6}}}}\right)$$

Now let's find a common denimator between these two fractions. I believe 30 is the lowest common multiple between these two fractions, so let's use that. (We can also reduce our fraction after we get an answer, so it's not the end of the world if you don't find the lowest common multiple.)

In this next step, I just multiplied the top and bottom of the first fraction by 6, and the top and bottom of the second fracion by 5.

$${\frac{{\mathtt{18}}}{{\mathtt{30}}}}{\mathtt{\,-\,}}{\frac{{\mathtt{20}}}{{\mathtt{30}}}}$$

$${\mathtt{\,-\,}}{\frac{{\mathtt{2}}}{{\mathtt{30}}}}$$

$${\mathtt{\,-\,}}{\frac{{\mathtt{1}}}{{\mathtt{15}}}}$$
