Answer 1

$[\frac{-7}{18}]*[\frac{15}{7}]-[1*\frac{1}{7}]+[\frac{1}{2}*\frac{1}{4}]$

Let's solve this question step by step.

We'll apply BODMAS and solve this question.

BODMAS is an acronym for ⇒

• Brackets
• Of
• Division
• Multiplication
• Addition
• Subtraction

According to the rule of BODMAS, we need to solve a problem accordingly.

$[\frac{-7}{18}]*[\frac{15}{7}]-[1*\frac{1}{7}]+[\frac{1}{2}*\frac{1}{4}]$

$\frac{-5}{6} -[1*\frac{1}{7}]+ [\frac{1}{2}*\frac{1}{4}]$

$\frac{-5}{6}-\frac{1}{7} +\frac{1}{2}*\frac{1}{4}$

$\frac{-41}{42} +\frac{1}{2}*\frac{1}{4}$

$\frac{-41}{42} +\frac{1}{8}$

LCM ⇒ 168

$\frac{-41*4}{42*4} +\frac{1*21}{8*21}$

$\frac{-164}{168} +\frac{21}{168}$

$\frac{-143}{168}$

∴ $[\frac{-7}{18}]*[\frac{15}{7}]-[1*\frac{1}{7}]+[\frac{1}{2}*\frac{1}{4}]=\frac{-143}{168}$
