Question

Question 5.
If $\frac{5}{8}$ = $\frac{20}{p}$, then the value of p is
(a) 23
(b) 2
(c) 32
(d) 16

Answer 1

(c)

Given $\frac{5}{8}$ = $\frac{20}{p}$
We know that, if two fractions $\frac{a}{b}$ and $\frac{c}{d}$ are equivalent then,

$a\times d=b\times c$
$\Rightarrow$$5\times p=8\times 20$
$\Rightarrow$p = $\frac{8\times 20}{5}$
$\Rightarrow$p = $\frac{160}{5}$ =32
Hence, the value of p is 32.
