EQUIVALENT

Fractions!!!


Monday april 9 th

To add or subtract unlike fractions, first rewrite them as equivalent fractions with a common denominator.

Remember!

Fractions that represent the same value are equivalent.


Monday april 9 th

How do we do this?

  • You can use any common denominator. But it will be easier to find the least common denominator to add and subtract unlike fractions.

  • The least common denominator (LCD) is the least common multiple of the denominators.


Time to and

Time to + and -!!!

Steps for unlike denominators

  • Find the LCD for the two denominators by looking for LCM

  • Make equivalent fractions by multiplying both the numerator and denominator by the same number (to get LCD)

  • Add the numerators, leave your denominator

  • If needed, simplify

Summary

Summary

In your groups, fill in the blanks

If I go to subtract my fractions and there isn’t a large enough fraction to subtract from I must ____________one of my fractions. To do this I subtract 1 from my _____________ number. Next, I __________my numerator and denominator, this is my new ____________________. This whole process is called _______________________________.
