Answer 1

3. Answer :

$\sf \frac{(x + y)}{(x - y)} = \frac{ \frac{5}{2} + ( \frac{ - 3}{4} ) }{ \frac{5}{2} - ( - \frac{3}{4} ) } = \frac{ \frac{5}{2} - \frac{3}{4} }{ \frac{5}{2} + \frac{3}{4} } = \frac{ \frac{10 - 3}{4} }{ \frac{10 + 3}{4} } = \frac{7}{ \cancel4} \times \frac{ \cancel4}{13} = \frac{7}{13}$

4. Answer :

$\sf 7 \frac{2}{3} m \: = ₹12 \frac{3}{4}$

$\sf \frac{14}{3} m = ₹ \frac{36}{4}$

$\sf \frac{14}{3} m = ₹9$

$\sf 1m \: = ₹9 \times \frac{3}{14} = \frac{27}{14} \implies \: \: 1m \: = \: ₹1.92$

6. Answer :

• 11(7y + 2) = 5(6y - 5)
• 77y + 22 = 30y - 25
• 77y - 30y = -25 - 22
• 47y = -47
• y = -47/47 = -1
• Value of y = -1

9. Answer :

• 3t - 9 = 10t - 5
• 10t - 3t = -9 -5
• 7t = -14
• t = -2
• Value of t = -2
