Question

गुणनफल ज्ञात कीजिए : (i)$\frac{9}{2} \times(\frac{-7}{4} )$(ii)$\frac{3}{10} \times(-9)$(iii)$\frac{-6}{5} \times\frac{9}{11}$(iv)$\frac{3}{7} \times( \frac{-2}{5})$(v)$\frac{3}{11} \times\frac{2}{5}$(vi)$\frac{3}{-5} \times\frac{-5}{3}$

Answer 1

Step-by-step explanation:

(i) दिया है : 9/2  × - 7/4

= (9 × - 7)/(4 × 2)

= - 63/8

 

(ii) दिया है : 3/10 × - 9

= (3 × -9)/10

= - 27/10

 

(iii) दिया है : - 6/5 ×  9/11

= ( - 6 × 9)/(5 × 11)

= - 54/55

 

(iv) दिया है : 3/7 × (- ⅖)

= (3 × - 2)/(7 × 5)

= - 6/35

 

(v) दिया है : 3/11 × ⅖

= (3 × 2)/ (11 × 5)

= 6/55

(vi) दिया है : 3/-5 × - 5/3

= (3 × - 5)/(-5 × 3)

= - 15/-15

= 1

Answer 2

$\Huge{\red{\underline{\underline{\rm{Solution}}}}}$

(i)$\dfrac{9}{2} \times(\dfrac{-7}{4} )$

$\implies$ $\dfrac{9}{2} \times \dfrac{ - 7}{4}$

$\implies$ $\dfrac{ - 63}{8}$

(ii)$\dfrac{3}{10} \times(-9)$

$\implies$ $\dfrac{3}{10} \times ( - 9)$

$\implies$ $\dfrac{ - 27}{10}$

(iii)$\dfrac{-6}{5} \times\dfrac{9}{11}$

$\implies$ $\dfrac{ - 6}{5} \times \dfrac{9}{11}$

$\implies$ $\dfrac{ - 54}{55}$

(iv)$\dfrac{3}{7} \times( \dfrac{-2}{5})$

$\implies$ $\dfrac{3}{7} \times \dfrac{ - 2}{5}$

$\implies$ $\dfrac{ - 6}{35}$

(v)$\dfrac{3}{11} \times\dfrac{2}{5}$

$\implies$ $\dfrac{3}{11} \times \dfrac{2}{5}$

$\implies$ $\dfrac{6}{55}$

(vi)$\dfrac{3}{-5} \times\dfrac{-5}{3}$

$\implies$ $\dfrac{3}{ - 5} \times \dfrac{ - 5}{3}$

$\implies$ $\dfrac{ - 15}{ - 15}$

$\implies$ $1$
