Question

Find 2/5* (- 3/7) - 1/14 - 3/7 x 3/5.
​

Answer 1

Answer:

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

-15/35 -1/14

-3/7 -1/14

(-6 -1 )/14

-7/14 = -1/2

Answer 2

The final answer after simplifying the above equation = $- \frac{1}{2}$

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

To simplify the above equation

Step by step explanation:

⇒ $- (\frac{2}{5} * \frac{3}{7}) - \frac{1}{14} - (\frac{3}{7} * \frac{3}{5})$
⇒ $- (\frac{6}{35}) - \frac{1}{14} - \frac{9}{35}$
⇒ $- (\frac{6}{35} + \frac{9}{35}) - \frac{1}{14}$
⇒ $- (\frac{15}{35}) - \frac{1}{14}$
⇒ $- (\frac{3}{7}) - \frac{1}{14}$
LCM of 7 and 14 = 14
Now making the denominator of both the terms = 14
⇒ $- (\frac{3 * 2}{7 * 2}) - \frac{1 * 1}{14 * 1}$
⇒ $- (\frac{6}{14}) - \frac{1}{14}$
⇒ $- (\frac{6}{14} + \frac{1}{14})$
⇒ $- (\frac{6 + 1}{14})$
⇒ $- (\frac{7}{14})$
⇒ $- \frac{1}{2}$

∴ The final answer after simplifying the above equation = $- \frac{1}{2}$
