Question

the product of three numbers is11/2 .if two of them are 16/7 and 11/8 , find the third​

Answer 1

$\huge\text{\underline{Answer}}$

Let the three numbers be a, b and c.

According to question

$\bold{a× b × c = \frac {11}{2}}$

$\bold{a= \frac {16}{7}}$

$\bold{b= \frac {11}{8}}$

Now,

$\implies$ $a \times b \times c = \frac{11}{2}$

Putting the value of a and b in equation.

$\implies$ $\frac{16}{7} \times \frac{11}{8} \times c = \frac{11}{2}$

$\implies$ $\frac{22}{7} \times c = \frac{11}{2}$

$\implies$ $c = \frac{22 \times 2}{11 \times 7}$

$\implies$ $\bold{c = \frac{4}{7} }$
