Answer 1

Question:

$\tt \dfrac{ - 1}{2} \div \dfrac{3}{4}$

Answer:

$\tt \dfrac{ - 1}{2} \div \dfrac{3}{4}$

• L.C.M of 2 and 4 = 2 × 2 = 4

Now , converting the denominators simultaneously by multiplying the value of denominator with L.C.M (4).

$\rightarrow \tt \dfrac{ - 1 \times 4}{2 \times 4} = \bf \dfrac{ - 4}{4}$

$\rightarrow \tt \dfrac{ - 4}{\not{4}} \div \dfrac{3}{ \not{4} }$

$\rightarrow \tt - 4 \div 3$

$\rightarrow \bf{ \red{1.33}}$

Answer 2

Answer:

$\frac{ - 1}{2} \div \frac{3}{4} \\ \frac{ - 1}{2} \times \frac{4}{3} \\ = \frac{ - 1}{_{1 \: \: } \cancel 2} \times \frac{ \cancel 4 _{ \: \: 2} }{3} \\ \boxed{ = \underline{ \underline{ \frac{ - 2}{3} }}}$
