Answer 1

Answer: 3 9/10 is the answer.

Step-by-step explanation:

1 1/2 + 2 2/5

= 3/2 + 12/5

= (taking LCM) 3*5/2*5 + 12*2/5*2

= 15/10 + 24/10

= (15+24)/10

= 39/10

= 3 9/10

Answer 2

Answer:

$3 \frac{9}{10}$

Step-by-step explanation:

$1 \frac{1}{2} + 2 \frac{2}{5}$

$\implies \: (1 + 2) + ( \frac{1}{2} + \frac{2}{5} )$

$\implies \: 3 + \frac{5 + 4}{10}$

$\implies \: 3 + \frac{9}{10}$

$\implies \: 3 \frac{9}{10}$
