Not necessarily. .The denominator for 1/3 + 1/5 is 15.
yes!! it is called unit fraction
If you double the denominator of any fraction, the number of unit fractions stays the same but each unit fraction is half as big. So the value of the fraction is half what it was when you double the denominator. 2×(5/8)=(2×5)/8=10/8
its always going to be in the denominator of 2 fractions.
Unit.
It is a unit rate.
A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n.
Unit fractions all have the same numerators but the denominators can be different.
Yes, every unit fraction is proper fraction because a proper fraction is a fraction in which the numerator is smaller than denominator. So the set of all unit fractions are also proper fractions.
They usually have a denominator of 1 although numerators of 1 are also possible.
A unit need not have any denominator.
In a fraction they must be in the same units. In a ratio they need not be.
A unit rate is a ratio in which the numerator or denominator is 1 unit.
