please,its very urgent. anwer will be marked as brainliest and will be followed.​

Answer 1

Step-by-step explanation:

a) Given,

$(2 \frac{1}{2}) + (3 \frac{1}{3}) + (5 \frac{1}{5} )$

$= \frac{5}{2} + \frac{10}{3} + \frac{26}{5}$

Taking L.C.M,

$= \frac{5 \times 15 + 10 \times 10 + 26 \times 6}{30}$

$= \frac{75 + 100 + 156}{30}$

$= \frac{331}{30}$

$= 11.03$

b) Given,

$4\frac{2}{5} \div 2\frac{2}{5}$

$= \frac{22}{5} \div \frac{12}{5}$

$= \frac{22}{5} \times \frac{5}{12}$

$= \frac{22}{12}$

$= 1.83$

Hopefully, that clears the doubt <3
