Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\frac{-4}{5}and\frac{7}{15}$$

Answer

-(28*a*n*d)/75

Solution


Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-\frac{4and\times 7}{5\times 15}\]
Simplify  \(4and\times 7\)  to  \(28and\).
\[-\frac{28and}{5\times 15}\]
Simplify  \(5\times 15\)  to  \(75\).
\[-\frac{28and}{75}\]
