What is a fraction that compares two quantities measured in different units?
A rate is a fraction that compares two quantities measured in different units. If the denominator of the fraction is 1 unit, the rate is called a unit rate.
Is a fraction a unit fraction?
No, every fraction is not a unit fraction because unit fraction must have 1 as numerator but every unit fraction is a fraction such as 2/3 is a fraction but not considered a unit fraction and 1/3 which is a unit fraction is also called fraction
Shall numerator and denominator in a fraction should be on the same unit of measurement or they can be on different unit of measurement?
In a fraction they must be in the same units. In a ratio they need not be.
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 is one technique used to convert a measurement in one unit into a different unit with out changing the value of the measurement?
Multiply the original quantity by a conversion factor, a fraction containing the desired unit in the numerator and the original unit in the denominator so that the fraction is equal to one.
