Question

Find the missing number

$\frac{10}{18}=\frac{n}{27}$

Answer 1

Step-1: Write $a,b,candd$as $\frac{10}{18}=\frac{n}{27}$is written in the form of $\frac{a}{b}=\frac{c}{d}$

$a=10$ $b=18$ $c=n$ $d=27$

Step-2: Write mean terms and extreme terms

$meanterms:-$ $b=18$ $c=n$

$extremeterms:-$ $a=10$ $d=27$

Step-3: use $onemean=\frac{productofextremes}{othermean}$ as one mean term is missing

$onemean=\frac{productofextremes}{othermean}$

$n=\frac{10\times 27}{18}$

$n=\frac{270}{18}$ ( simplify $\frac{270}{18}$by dividing by a common factor $18$in numerator and denominator separately )

$n=15$

Hence, the missing number is $n=15$
