How do you do perimeter with fractions?
just find a common denominator and add like you regularly would with fractions.
How are like fractions and unlike fractions different?
Like fractions have the same denominator, unlike fractions don't.
Why do you need equivalent fractions?
What would our world be like without fractions? Our language would certainly change! You could never tell a friend to break a cookie in "half" to share with you. You could only tell them to break it into two pieces. A glass containing water could never be described as "half full." How could you describe this glass? There would be no such thing as "half past the hour" with timekeeping. You could never say you are "halfway" there when traveling. Obviously, fractions are truly an important part of our language. They are equally important for mathematics. the reason you need equivalent Fractions is because that it is the only way to add or subtract fractions. You do not need equivalent fractoins when you multiply or divide though
What do like and unlike fractions mean?
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
What is the difference between unlike fractions and like fractions?
that they dont looks like them
