Happy Monday and welcome back everyone! I am in a great mood today because I got 15/15 on my spanish test! Studying really does work! Anyways, today we will be talking about negative numbers and when we see and use them in real life. 
     Negative numbers are numbers to the left of zero on a number line. You'll see negative numbers with negative signs that look like this... - . For example, here is negative eight, -8. Negative eight's absolute value is positive eight, +8, or 8! Negative numbers are used to tell how less of something you have or how far away you are from zero in a negative way. For example, we use this today... when you're scuba diving three feet away from the surface of the ocean you're -8 down. If you go to the bank and owe 25 dollars.... that's -25. Negative numbers aren't that hard when you think about it. Just remember that they are always to the left of zero on a number line and they have negative signs!!!!!!!!!!!!!!
 
    Welcome back and happy Monday! I hope everyone's weekend was fun and will talk about mine later on Free-Write Friday. Today we are going to "discuss" how to solve the equation "2x-7=15." Here, we go... 
#1 Figure and Define.
2,7, and 15 are all digits
- means we are going to subtract
"x" is just a variable. It could be any imaginable number. 


#2 Solve (Now that we know what everything is)
2x-7=15 
YOU HAVE TO GET THE VARIABLE (x) ALONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So, subtract 2 from each side. 2-2=0 and 15-2=13
Now we have       x-7=13

#3 Finish it off
Since 7 is -7 in this case, we will add to get zero (negative plus positive is zero if its the same number)
-7+7=0 and 13+7=20
Now we have x=20


#4 Double-Checker
Double check your work and make sure all your numbers are correct.
I've double checked my work and i know it to be true. 
x=20


Horray!!!!!!!!!!!!!!!!!!!
 
     Happy Monday everyone and welcome back to "Katie's Contemplations Math Monday Blogs." I hope everyone is ready to learn some math because today we have a great topic! Here's our main question... "How do you convert a decimal into a fraction?"


Let's start here...
.1 = 1/10      .01 = 1/100       .001 = 1/1000     .0001 = 1/10000
Get it? It's ok if you don't... I didn't describe it that well. Here, if you have .50 of a pizza, that mean you have 1/2. If you have .75 of the pizza, that means you have 3/4 of the pizza. Think about it this way, how much money is a quarter worth? That's right, 25 cents or .25. How many quarters does it take to make a dollar? 4, because 25 + 25 + 25 + 25 = 100. Now let's say that we put a decimal place in-front-of 25 so now it's .25. Add .25 together four times and get 1.00. So when you have a decimal in the tenth place, like this .2, put it over a ten... 2/10 (or simplified 1/5.)  When the the number is in the hundreths place like this, .02, put it over one hundred... 2/100. Just work hard and ask questions and you'll for sure get it.
