Lets get started with the first fraction: 2/3 and 4/6. Is 2/3 bigger than 4/6, smaller, or the same? Well, lets get started with finding the decimal of the two different fractions.
DECIMAL:Divide 2 by 3 and you get o.666(repeating) and when you divide 4 by 6 you get 0.666(repeating)
looks the same, right? That's because they are the same, which also means that they're equivalent. But, 4/6 is more precise: accurate or correct.
Now, lets get started on the second fraction: 1/8 and 1/4. Is 1/8 bigger than 1/4, smaller, or the same? Lets do exactly the same as the last time, lets find out the decimal.
DECIMAL: Divide 1 by 8 and you get o.125 and when you divide 1 by 4 you get 0.25.
You can see that 1/4 is bigger than 1/8... because lets pretend that you have two cakes, one cake is cut into four pieces, and the other cake is cut into eight pieces. The cake that got cut into four pieces would have bigger pieces than the one cut into eight pieces.
