A fraction is a numerical expression representing a part of a larger whole.
An unlike fraction is a fraction that have different denominators. Example: 3/4 and 2/3 Three-fourths and two-thirds are unlike fractions.
A greatest common factor is the largest number that is a common factor of two or more numbers.
Hope that helps!
A like fraction is a fraction with the same denominator, meaning that the number at the bottom of the fraction is the same for multiple fractions. For example, 1/4 and 3/4 are like fractions because they both have a denominator of 4.
To find the greatest common factor (GCF) of two or more numbers, you need to determine the largest number that evenly divides all the given numbers without leaving a remainder. For example, to find the GCF of 12 and 18, you can list the factors of both numbers:
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9, 18
From this list, you can see that the largest number that appears in both lists is 6. Therefore, the greatest common factor of 12 and 18 is 6.
On the other hand, unlike fractions have different denominators. For example, 1/4 and 3/5 are unlike fractions because they have different denominators (4 and 5, respectively).
To add or subtract unlike fractions, you need to convert them into like fractions by finding a common denominator. The common denominator is the smallest multiple of both denominators. Once you have like fractions, you can perform the addition or subtraction operation.
I hope this explanation helps you understand the concepts of like fractions, greatest common factor, and unlike fractions!
