Operations on Rational numbers
Addition rational numbers :
Steps used for addition rational-numbers :
1) In a rational number, if the denominators are same then just add the numerators.
p / q + r / q = ( p + r ) / q
2) If the denominators are different then first find the LCM of denominators, make the denominators same and then add the numerators.
________________________________________________________________ Some solved examples on addition rational numbers Same denominators :
1) 12 / 7 + 23 / 7 = ( 12 + 23 ) / 7 = 35 / 7
As the GCF(HCF) of 35 and 7 is 7 so we can write this rational number in lowest form.
