Question

solve -2/3+[3/5+(-5/6)]. ​

Answer 1

$\huge{QUESTION :-}$

solve -2/3+[3/5+(-5/6)]

$\huge{ANSWER :-}$

$\red{★} \: \frac{ - 2}{3} + ( \frac{3}{5 } + ( \frac{ - 5}{6} ))$

According to BIOMAS Bracket first to solve

★ LCM OF 5 AND 6 is 5×6 = 30

so,

$\red{★} \: \frac{3}{5} \times \frac{6}{6} = \frac{18}{30} \: \: \:$

$\red{★} \: \frac{ - 5}{6} \times \frac{5}{5} = \frac{ - 25}{30}$

$\red{★} \: \frac{18}{30} + \frac{ - 25}{30} = \frac{ - 7}{30}$

now we completed bracket next we should add -2/3

before we should find the LCM of 3 and 30 is 30

$\red{★} \: \frac{ - 2}{3} \times \frac{10}{10} = \frac{ - 20}{30}$

$\red{★} \: \frac{ - 20}{30} + \frac{ - 7}{30} = \frac{ - 27}{30}$

the answer is -27/30 but we can simply

$\huge \red{ \red{★}} \: \frac{ - 27}{30} = \frac{ -9 }{10}$
