  2. Now, click the "EQUIVALENT FRACTIONS WORKSHEET" and do the exercises.

NOW IT'S TIME TO LEARN MORE...

See the video bellow

a) Fractions with the same denominator: To sum/subtract fractions with the same denominator all you have to do is to sum/subtract the numerators and maintain the common denominator.

 

b) Fractions with different denominators: If the denominator is not the same, first you have to change the fractions for other representing the same rational numbers but with THE SAME denominator. After that you proceed as before.

12 is the lowest common multiple of 6, 4, 3... that’s our new common denominator and we operate with three equivalent fractions!

AND MORE...

See the video bellow

a) To multiply fractions all you have to do is multiply the numerators (to obtain the new numerator) and multiply the denominators (obtaining the new denominator).

b) To divide fractions you multiply the numerator of the first fraction by the denominator of the second one (so you obtain the new numerator) and multiply the denominator of the first fraction by the numerator of the second one (obtaining the new denominator).

and if you simplify the final result is
