Question

2/5 * (-3/7) -1/6 * 3/2 + 1/14 * 2/5
solve this question using properties

Answer 1

Your answers is given below -----》》》

Answer:

- 1/2

Step-by-step explanation:

Given Using appropriate properties evaluate 2/5*-3/7-1/14-3/7*3/5

We can write this as

(2/5)(- 3/7) - 1/14 - (3/7)(3/5) Using commutative property

we can also write it as

3/7(- 2/5 - 3/5) - 1/14 (distributive property)

3/7(-5/5) - 1/14

3/7(- 1) - 1/14

3/7(- 1) - 1/14

- 3/7 - 1/14

- 1/2

If the question is 2/5 - 3/5. - 1/14. - 3/7. 3/5

- 6/25 . - 1/14 . - 9/35

   - 84 - 25 - 90 / 350

   = - 199 / 350

Answer 2

$\mathbf{[\frac{2}{5}*(\frac{-3}{7} )] -(\frac{1}{6}*\frac{3}{2})+ (\frac{1}{14}*\frac{2}{5} )}$

$\mathbf{=(\frac{-6}{35})-(\frac{3}{12} )+(\frac{2}{70} ) }$

$\mathbf{=(\frac{-6}{35})-(\frac{1}{4})+(\frac{1}{35} )}$

$\mathbf{=\frac{-6+1}{35}-\frac{1}{4} }$

$\mathbf{=\frac{-5}{35}-\frac{1}{4} }$

$\mathbf{=\frac{-1}{7}-\frac{1}{4}}$

$\mathbf{\frac{-4-7}{28} }$

$\mathbf{\bold{\redyellow{\boxed{=\frac{-11}{28} }}}}$
