Sum= 18/5 + (-7)/15 ( By Taking lcm )
= 54/15 + (-7)/15
= 47/15
now let the rational no. be x
Therefore According to question:
47/15 ÷ x = 47/6
47/15 = 47/6× x
47/15 × 6/47 = x
x = 2/5
Therefore the rational is 2/5
= 54/15 + (-7)/15
= 47/15
now let the rational no. be x
Therefore According to question:
47/15 ÷ x = 47/6
47/15 = 47/6× x
47/15 × 6/47 = x
x = 2/5
Therefore the rational is 2/5
