Question
By what number should $9\frac{4}{5}$be multiplied to get $42$?
✓
Answer
product of two numbers $= 42$
One number $=9\frac{4}{5}=\frac{49}{5}$
$\therefore$ Second number $=42\div\frac{49}{5}=42\times\frac{5}{49}$
$=\frac{6\times5}{7}=\frac{30}{7}=4\frac{2}{7}$
One number $=9\frac{4}{5}=\frac{49}{5}$
$\therefore$ Second number $=42\div\frac{49}{5}=42\times\frac{5}{49}$
$=\frac{6\times5}{7}=\frac{30}{7}=4\frac{2}{7}$
