Get a common denominator and add / subtract.
Example: (1/8) + (2/8) = Since they are the same denominator, add (3/8)
Example: (1/8) - (2/8) = (-1/8)
Example: (1/8) + (1/4) = They are not same denominator so:
Multiply one of the fractions by a factor over a factor (x/x) to make it the same denominator!
(1/4) * (2/2) = (2/8)
(1/8) + (2/8) = (3/8)
Example: (1/8) + (1/7) = If they are not easily factored, just use this trick:
Multiply the left fraction by the right denominator and the right fraction by the left denominator
(1/8) * (7/7) = 7/56
(1/7) * (8/8) = 8/56
7/56 + 8/56 = 15/56
Answer:
Rational numbers are just numbers that can be divided and made into 2 integers.
Step-by-step explanation:
Rational numbers can be the following and more:
•1/2 is a rational number (1 divided by 2, or the ratio of 1 to 2)
• 0.75 is a rational number (3/4)
• 1 is a rational number (1/1)
• 2 is a rational number (2/1)
• 2.12 is a rational number (212/100)
• −6.6 is a rational number (−66/10)
• etc
The reason for this is because these numbers can be multiplied and made into 2 Integers.
