Are all fractions that have a numerator of 1 in simplest form explain?
Yes, that is true. With all positive fractions that can be reduced, the numerator becomes a smaller positive whole number. There is no smaller positive whole number than one, therefore all fractions that have a numerator of 1 are in their simplest form. You can tell if a fraction is in its simplest form by finding the the GCF of the nmerator and the denominator. If the GCF is 1, the fraction is in its simplest form. The GCF of any number and 1 is 1, therefore all fractions that have a numerator of 1 are in their simplest form.
Are all fractions that have a numerator of 1 in simplest form?
Basically yes. If you want to be pedantic about it, though, there is the exception when the denominator is negative. Convention requires the simplest form to have a negative numerator (-1) and a positive denominator.
How are all unit fractions different?
They have the same numerator (1) but different denominators. Since the numerator is 1 in each fraction, it cannot be simplified therefore each unit fraction is in its simplest form. Then, because the denominators of any two of them are different the fractions must be different.
What do you notice about equivalent fractions?
When they are all converted to simplest form, they are all the same.
What are all the equivalent fractions of 18 20?
There are an infinite number of equivalent fractions. The simplest form is 9/10.
