9/10

4/5

First, you need to find the Least Common Multiple (LCM)

In this case, it would be the 10, because you can multiply 5 by 2 get to 10, and you can multiply 10 by 1 to get 10.

But, you don't just multiply the 5 by 2. Since we have to make it equal, you also have tomultiply the 4 by 2

Ohh, so it would be 8/10!And since 9/10 is bigger than 8/10 (Because the numerator is bigger and the denominator is equal) the equation is correct!

Some Handy Tips and TricksFirst, you should always look at the whole number. If the whole is bigger, then the number is bigger.2nd, you should look at the denominator. Usually if the denominator is smaller, the number is bigger.

Then, If the denominator and the whole number are equal, look at the numerator.If the numerator is bigger, and the denominators + whole numbers are equalthat number is greater. But, if everything is equal, that number is equivalent.

You should also look at the relationship between the numbers and 0 and 1 whole.

Fractions: Lesson 4

Subtracting!

And...

With Fractions!

You have find the common denominator to add the 2 fractions together.

Then, all you have to dois add the numerators andkeep the denominators.

5/9 - 1/3

Again, find the common denominator to subtract the fractions.

In this case, it would be 9, so the equation would be 5/9 - 3/9. Finally subtract the numerators and keep thenumerators.

For a improper fraction, first you convert it to a mixed number. Then you look at which whole is bigger. The improper fraction is always bigger than the proper one.
