by crossing out numbers like it it is 7/14 * 2/5= 7/35
You cross out when you see the same number as a factor on top and bottom.
e.g.: 2/2 simplifies to 1
4/2 = (2x2)/2 = 2
12/6 = (2x2x3)/(2x3) = (2x3)/3 = 2

Adding mixed numbers with unlike denominators?
First convert the mixed numbers into "top heavy (or "improper) fractions". Now multiply each of the improper fractions by each other - this makes the denominators the same. Now you can add both the fractions together (and cancel down if necessary).
What do you know about rational numbers and making them equivalent?
Rational numbers can be expressed as fractions and fractions can be equivalent as for example 3/4 has the same value as 9/12
Why do you need to know about integers?
What you need to know about integers is that integers is the name for the group of numbers that include whole numbers and negative numbers. But integers DO NOT include fractions.
What do fractions help with?
Fractions help with numbers that are not whole numbers.
How do you divide fractions with common denomonators?
switch numbers and multiply you should know that

How do you divide fractions with whole numbers?
I honestly do not know.
What do you know about rational numbers?
All rational numbers can be expressed as fractions whereas irrational numbers can't.
How do you know when two fractions are equal?
If the denominators (bottom numbers) are not equal, making equivalent fractions of them so that the denominators are equal. With the denominators equal if the numerators (top numbers) are equal, then the fractions are equal.

Are fractions whole numbers?
No. All fractions are not whole numbers, but all whole numbers are [improper] fractions (with a denominator of 1).
How can you cancel down fractions?
By dividing the numerator and denominator by their HCF
How do you do dividing fractions and mixed numbers?
You change the mixed number into an inproper fraction.
What fractions are rational numbers?
All fractions are rational numbers.
