Okay, so remember those equivalent fractions from last week? I hope you didn't think you were finished with those, because there are a bunch more coming for you this week! The reason for this is because we need to use equivalent fractions to find a denominator (the bottom number) that is either 10 or 100. This is a tricky task to explain by typing it on a computer, so take a look at the video below. It gets a little more complicated after 2:50 in the video, so you can stop there if you find that the next stuff gets a bit confusing!
So the bottom line, is that in order to turn a fraction into a decimal is to find a denominator that is 10 or 100, then write that fraction as a decimal. Sometimes, the denominator doesn't multiply by any number evenly in order to find a denominator that is 10 or 100, but luckily, we don't look at these types of questions this year. Below are so quick tricks to remember what to multiply something by to get the denominator you need:
I have good news! Going the other way, where you are given a fraction and must turn it into a decimal, is much easier! There are only two steps:
1. take a look at the decimal, and decide if it is tenths or hundredths.
(If there is only one number after the decimal point, it is tenths. For example, 0.7 is seven tenths)
(If there are two numbers after the decimal point, it is hundredths. For example, 0.44 is forty-four hundredths)
2. Write the number in the decimal over the number that you identified, as pictured below:

Alright - this is tricky stuff, but once you get it, it goes much easier. This week, I'd like you to do the practice below.

Now normally, I would make this project an assignment for a week, but, well, we are running out of time! Did you realize that next week is the last week of work for you guys before summer vacation?! So, since you have already put in so much work into math already this week, I will make this final project optional. It is good practice though, and I think it is lots of fun!
