Question

if the sum and difference of two fractions are 56/27 and 16/27 respectively then their L C M is​

Answer 1

Step-by-step explanation:

x+y=56/27---------(1)

x-y=16/27-----------(2)

2x=(56/27)+(16/27) (add (1) and (2) )

=(56+16)/27

=72/27

x=(72/27)*1/2

=36/27

=4/3

(36/27)+y =56/27 (from (1) )

y =(56/27)-(36/27)

=(56-36)/27

= 20/27

LCM of 4/3 and 20/27 = 20/3 (LCM of fraction = lcm of the numerator/ gcd of the denominator)
