Question

Simplify the following 3/4(1/2× - 12)+4/5

Answer 1

Answer:

The value of $\frac{3}{4}\left(\frac{1}{2} \times-12\right)+\frac{4}{5}$ is -$\frac{37}{10}$ or (-3.7)

Solution:

$\frac{3}{4}\left(\frac{1}{2} \times-12\right)+\frac{4}{5}$

Simplifying the equation we get,

$\left(\frac{3}{4}\right) \times\left(\frac{1}{2} \times(-12)\right)+\frac{4}{5}$

$\left(\frac{3}{4}\right) \times\left(\frac{-12}{2}\right)+\left(\frac{4}{5}\right)$

Dividing -12 and 2,

$[(\frac{3}{4})\times(-6)]+ (\frac{4}{5})$

$\frac{3 \times(-6)}{4}+\left(\frac{4}{5}\right)$

$\frac{-18}{4}+\left(\frac{4}{5}\right)$

Bringing $\frac{-18}{4}$ to its simplest form of fraction,

$\left(-\frac{9}{2}\right)+\left(\frac{4}{5}\right)$

$\left(\frac{4}{5}\right)-\left(\frac{9}{2}\right)$

Factors of 5 = $5\times1$

Factors of 2 = $2\times1$

Therefore, Least Common multiple of 5 and 2 is 10.

$\frac{8-45}{10}$

$-\frac{37}{10} = (-3.7)$
