What is a fraction?
A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in the numerator or denominator.
Adding and Subtracting Fractions
To add or subtract fractions they must have the same denominator (the bottom value). If the denominators are already the same then it is just a matter of either adding or subtracting the numerators (the top value).
There are multiple ways to solve a fraction like solving it in main fraction form and solving it in decimal form.
Answer in Adding a Fraction:
1. 7/12 + 8/12 = 7+8/12 = 15/12 = 5/4
2. 6 2/5 + 4 2/3 = (6 + 4) + ( 2/5 + 2/3 ) = 10 + 1 1/15 = 11 1/15 or 166/15
3. 4 3/4 + 5 2/7 = (4 + 5) + ( 3/4 + 2/7 ) = Wwait lang po kakain lang, sinave kko lang281/28
4. 3 1/2 + 2 5/8 = 49/8
5. 4/5 + 7 1/5 = 8
All fraction is in simplified form.
Answer in Subtracting a Fraction:
1. 16/21 - 9/21 = 1/3
2. 9 3/4 - 5 3/8 = 35/8
3. 4 7/10 - 1 2/5 = 33/10
4. 5 4/8 - 2 7/8 = 21/8
5. 7 5/6 - 1 4/5 = 181/30
All fractions are in simplified form
