Can you prove that pi is an irrational number? Well, that's one thing that we learned in class today. On your calculator put in: π then =. You should get 3.141592654. Now divide π by 100000000. *gasp* Did you get pi as an answer? That's because there are a limited amount of characters on your calculator and it can't calculate the full number.
Today we also learned about Equivalent Fractions. Equivalent Fractions are fractions that mean the same thing. In other words have the same value in decimal form. An example of an equivalent fraction is 10/20=1/2=5/10=100/200=0.5
Sometimes when we see something written differently we almost automatically think that they are different from each other. There are many different ways to write the same fraction. So, next time you compare fractions..check to make sure they aren't equivalent.
REMEMBER: The sum of opposites=Zero. Why? Because they are Zero Pairs, which means they cancel each other out. 365+(-365)=0
