My terrible thing xD.

2/3 and 4/6
two easy ways to find that they are equal :].
First look you can convert into %'s. How you can do this is you take 100 and divide it by the denominator. So you would split 100 into 3 parts and into 6 parts. When dividing 100 into 3 parts its 33.333 on going but we just say 33.3. So 1 part is 33% add another part to that and it equals 66%. 66% is when you have 2 thirds of a number. Finally you do the same thing to the 4/6 each part is around 16.6% on going so when you add two together its about 33.3 % 2/6 is equal to 1/3 add 2 to 2/6 which is another 30% and you have 2/3 and 4/6 being the same number [ 66% ].

Another way is simplying.
all you have to do is find out if you are able to half the numerator and denominator with it still being a whole number.
When you half 4/6 4 divided by 2 and 6 divided by 2 it is equal to 2/3 which is obviously equal to 2/3.

2 different ways to find which is greater between
1/8 and 1/4
For this you are definetly able to convert into %'s.
you know that 1/4 is 1 quarter of 100. Divide 100 by 4 and that equals 25%. 1/8 is half of 1/4 so that means that it is half of 25. 1/8 is equal to 12.5% which means for sure that 1/4 is bigger.

In decimals this may be a little confusing for some people

0.125 [1/8]
0.25 [1/4]

as you can see the 1/8 looks bigger. But it is not. This is something called place values. here is the example.


It doesnt matter how many 0's are behind it the closest place value to the whole is whats determined to find the real answer.

okay I hope this made sense.
