Question

Please anybody give me answer very quick​

Answer 1

Step-by-step explanation:

-1/2×3/5 + 3/2 - 3/5 × 5/4

= -3/10 + 3/2 - 3/4

= -3/10 + (6-3)/4

= -3/10 + 3/4

= (-12+30)/40

= 18/40

= 9/20

Answer 2

$\large \underline{ \underline{ \bf Question} }:$

$\sf \dfrac{ - 1}{2} \times \dfrac{3}{5} + \dfrac{3}{2} - \dfrac{3}{5} \times \dfrac{5}{4} = ?$

$\large \underline{ \underline{ \bf Solution} }:$

$\sf : \implies \dfrac{ - 1}{2} \times \dfrac{3}{5} + \dfrac{3}{2} - \dfrac{3}{5} \times \dfrac{5}{4}$

$\sf : \implies \dfrac{ - 1 \times 3}{2 \times 5} + \dfrac{3}{2} - \dfrac{3 \times 5}{5 \times 4}$

$\sf : \implies \dfrac{ - 3}{10} + \dfrac{3}{2} - \dfrac{15}{20}$

$\sf : \implies \dfrac{ - 3 \times 2}{10 \times 2} + \dfrac{3 \times 10}{2 \times 10} - \dfrac{15}{20}$

$\sf : \implies \dfrac{ - 6}{20} + \dfrac{30}{20} - \dfrac{15}{20}$

$\sf : \implies \dfrac{ - 6 + 30 - 15}{20}$

$\sf : \implies \dfrac{ - 21 + 30}{20}$

$\sf : \implies \dfrac{9}{20}$

$\tt Hence, \: \dfrac{ - 1}{2} \times \dfrac{3}{5} + \dfrac{3}{2} - \dfrac{3}{5} \times \dfrac{5}{4} = \pink{ \dfrac{9}{20} }$
