Question

guys please amswer fast..and please do not spam..please ..and do Q3 and 4..please ​

Answer 1

Answer:

1. -1
2. $\sf \frac{19}{56}$
3. $\sf \frac{ -52}{45} \: or \: - 1\frac{7}{45}$
4. 8

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Q1 ➸ $\sf \frac{5}{4} + (- \frac{9}{4})$

$\sf→\frac{5}{4} - \frac{9}{4}$

$\sf→\frac{5 - 9}{4}$

$\sf→\frac{- \cancel{4}}{\cancel{4}}$

$\sf→\fbox{ - 1}$

∴ The answer is -1.

Q2 ➸ $\sf \frac{5}{7} - \frac{3}{8}$

L.C.M. of 7 and 8 is 56.

$\sf→ (\frac{5}{7} \times \frac{8}{8}) - (\frac{3}{8} \times \frac{7}{7})$

$\sf→ \frac{40}{56} - \frac{21}{56}$

$\sf→ \frac{40 - 21}{56}$

$→ \boxed{\sf \frac{19}{56}}$

∴ The answer is $\sf \frac{19}{56}$.

Q3 ➸ $\sf - \frac{8}{9} \div \frac{ - 4}{15}$

$\sf→ \frac{(- \frac{8}{9})}{(\frac{ - 4}{15})}$

➸ Reciprocal the terms,

$\sf→ \frac{\cancel{(- 8)} \times 15}{9 \times \cancel{(- 4)}}$

$\sf→ \frac{2 \times \cancel{15}}{\cancel{9} \times 1}$

$→ \sf \frac{2 \times 5}{3}$

$→ \boxed{\dfrac{10}{3}}$

∴ The answer is $\sf \frac{10}{3}$.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Q4 ➸ $\sf \frac{36}{7} \times \frac{14}{9}$

Canceling out the terms,

$\sf→ \frac{\cancel{36}}{7} \times \frac{14}{\cancel{9}}$

$\sf→ \frac{4}{\cancel{7}} \times \frac{\cancel{14}}{1}$

$\sf→ \frac{4}{1} \times \frac{2}{1} = 4 \times 2$

$\sf→\fbox{8}$

∴ The answer is 8.
