Answer 1

Answer:

-2/3×3/5+5/2-3/5×1/6

-6/15+5/2-3/30

-6/15+5/2-1/10

l.c.m=30

(-36+75-3)/30

46/30=23/15

Answer 2

Solution :

ㅤ

$\large\sf \implies - \dfrac{2}{\cancel3} \times \dfrac{\cancel3}{5} + \dfrac{5}{2} - \dfrac{\cancel3}{5} \times \dfrac{1}{\cancel6}$

ㅤ

$\large\implies \sf- \dfrac{2}{5} + \dfrac{5}{2} - \dfrac{1}{10}$

ㅤ

$\large\implies \sf\dfrac{ - 4 + 25 - 1}{10}$

ㅤ

$\large\implies \sf \dfrac{20}{10}$

ㅤ

$\large \implies \boxed{ \sf \: \: \: \: \: \sf2 \: \: \: \: \: }$
