Answer 1

Given:$-\frac{3}{4} +\frac{1}{2}$

We have to find$-\frac{3}{4}+\frac{1}{2} =?$

Let,

$=>-\frac{3}{4} +\frac{1}{2} =x\\=>x=\frac{-(3\times2)+(4\times1)}{4\times2} \\\\=>x=\frac{-6+4}{8} \\\\=>x=-\frac{1}{4}$

Hence, the correct answer will be$-\frac{1}{4}$.

Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

$\displaystyle \sf{ - \frac{3}{4} + \frac{1}{2} } \: \: is \: equal \: to$

$\displaystyle \sf{ 1. \: \: - \frac{1}{4} }$

$\displaystyle \sf{ 2. \: \: \frac{1}{2} }$

$\displaystyle \sf{ 3. \: \: - \frac{1}{2} }$

$\displaystyle \sf{ 4. \: \: \frac{1}{4} }$

EVALUATION

$\displaystyle \sf{ - \frac{3}{4} + \frac{1}{2} }$

The fractions are

$\displaystyle \sf{ - \frac{3}{4} \: \: and \: \: \frac{1}{2} }$

Numerator are - 3 & 1 respectively

Denominator are 4 & 2 respectively

LCM of the denominators = 4

Thus we have

$\displaystyle \sf{ - \frac{3}{4} + \frac{1}{2} }$

$\displaystyle \sf{ = \frac{ - 3 + 2}{4} }$

$\displaystyle \sf{ = \frac{ -1}{4} }$

$\displaystyle \sf{ = - \frac{1}{4} }$
