Question

simplify these two questions​

Answer 1

Step-by-step explanation:

1》let the no.=x

so ATQ

${ \frac{1}{2} }^{ - 1} \times x = { \frac{ - 5}{9} }^{ - 1} \\ x = { \frac{ - 5}{9} }^{ - 1} \times \frac{1}{2} \\ x = \frac{ 9}{ - 5} \times \frac{1}{2} = \frac{9}{ - 10}$

so no.=(-9/10)

2》

a》

$\frac{3}{4} \times \frac{?}{?} = \frac{ - 15}{?} \\ \frac{3 \times 5}{4 \times 5} = \frac{ - 15}{20}$

B》

$\frac{3}{4} \times \frac{?}{?} = \frac{36}{?} \\ \frac{3 \times 12}{4 \times 12} = \frac{36}{48}$

so this is the answer mark me brainliest
