One number is four times another number. The sum of their reciprocals is 1/4 . What is the answer
Yakvenalex [24]
Using the information from the question, one can construct two equations:

4 z = x  ...  (1)

\frac{1}{z}  +   \frac{1}{x}   ... (2)

by substituting (1) into (2) to find x

\frac{1}{z} +  \frac{1}{4z}  =   \frac{1}{4}

\frac{5}{4z}  =   \frac{1}{4}

\frac{5}{4z}  =   \frac{1}{4}  

\frac{4z}{5}  =   \frac{4}{1}

\frac{4z}{1}  =   \frac{20}{1}

z =   \frac{20}{4}

⇒ z = 5

By substituting value of z into (1)

⇒ 4 (5) = x

⇒ x = 20

Thus the two numbers are 5 & 20
