Question

By what number should 21/4be multiplied to get 1 1/2 ?

Answer 1

Answer:

$\frac{22}{21}$

Step-by-step explanation:

let the number be x

so, $\frac{21}{4} * x = \frac{11}{2}$

     x = $\frac{11}{2}$ ÷ $\frac{21}{4}$

     x = $\frac{11}{2} * \frac{4}{21}$

     x = $\frac{11}{1} * \frac{2}{21}$

     x = $\frac{22}{21}$
