Example

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

Question

$$THERATIONALNUMBERSBETWEEN-1/5AND1/2$$

Answer

THERATIONALNUMBERSBETWEEN-AND/10

Solution


Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[THERATIONALNUMBERSBETWEEN-\frac{1\times AND\times 1}{5\times 2}\]
Simplify  \(1\times AND\times 1\)  to  \(AND\).
\[THERATIONALNUMBERSBETWEEN-\frac{AND}{5\times 2}\]
Simplify  \(5\times 2\)  to  \(10\).
\[THERATIONALNUMBERSBETWEEN-\frac{AND}{10}\]
