Question

$$4/5OR3/7WHICHISSMALLER$$

Answer

(12*OR*WHICHISSMALLER)/35

Solution


Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{4OR\times 3WHICHISSMALLER}{5\times 7}\]
Simplify  \(4OR\times 3WHICHISSMALLER\)  to  \(12ORWHICHISSMALLER\).
\[\frac{12ORWHICHISSMALLER}{5\times 7}\]
Simplify  \(5\times 7\)  to  \(35\).
\[\frac{12ORWHICHISSMALLER}{35}\]
