Question

Simplify 2/5*-3/7-1/14-3/7*3/5 by using properties

Answer 1

$\bold{Answer :}$

Now,

2/5 * - 3/7 - 1/14 - 3/7 * 3/5

= (2/5) (- 3/7) - 1/14 - (3/7) (3/5)

= - 6/35 - 1/14 - 9/35

= (- 12 - 5 - 18)/70, since LCM (35, 14, 35) = 70

= - 35/70

= $\bold{- 1/2}$

Answer 2

The simplified form of the equation is $\frac{-1}{2}$.

Given:

$(\frac{2}{5}) (\frac{-3}{7}) -\frac{1}{14} -(\frac{3}{7})( \frac{3}{5})$

To Find:

The solution for the given problem

Solution:

We can simply solve this problem by using the following mathematical process.

Let us first solve the brackets.

Then,

$\frac{-6}{35} -\frac{1}{14} -\frac{9}{35}$

Now,

$(\frac{-6}{35} -\frac{9}{35})-\frac{1}{14}$

$\frac{-15}{35} -\frac{1}{14}$

Now, the LCM of 14 and 35 is 70.

Using the LCM we get,

$\frac{-30}{70} -\frac{5}{70}$

$\frac{-35}{70}$

$\frac{-1}{2}$

Hence, the correct answer is $\frac{-1}{2}$.
