Answers
Answer:×7−3−141−73×53=−21
Step-by-step explanation:
Given : Expression \frac{2}{5}\times \frac{-3}{7} -\frac{1}{14}-\frac{3}{7}\times\frac{3}{5}52×7−3−141−73×53
To find : The expression using appropriate properties ?
Solution :
\frac{2}{5}\times \frac{-3}{7} -\frac{1}{14}-\frac{3}{7}\times\frac{3}{5}52×7−3−141−73×53
Applying commutative property, a+b=b+aa+b=b+a
=\frac{2}{5}\times \frac{-3}{7}-\frac{3}{7}\times\frac{3}{5} -\frac{1}{14}=52×7−3−73×53−141
Applying distributive property, ab+ac=a(b+c)ab+ac=a(b+c)
=\frac{-3}{7}(\frac{2}{5}+\frac{3}{5})-\frac{1}{14}=7−3(52+53)−141
=\frac{-3}{7}(\frac{5}{5})-\frac{1}{14}=7−3(55)−141
=-\frac{3}{7}-\frac{1}{14}=−73−141
Taking LCD and solve,
=\frac{-6-1}{14}=14−6−1
=\frac{-7}{14}=14−7
=\frac{-1}{2}=2−1
Therefore, \frac{2}{5}\times \frac{-3}{7} -\frac{1}{14}-\frac{3}{7}\times\frac{3}{5}=-\frac{1}{2}52×7−3−141−73×53=−21
