Question

How many ft are in 1.3 centimeters

Answer 1

let's bear in mind that one foot is 12 inches, and 1 inch is about 2.54 cm.

then in 12 inches that'll be 12 * 2.54 cm, or namely 30.48 cm.

so, if there are 30.48 cm in 1 foot( 12 inches ), how many feet in 1.3 cm?

$\bf \begin{array}{ccll} feet&cm s\\ \cline{1-2} 1&30.48\\ f&1.3 \end{array}\implies \cfrac{1}{f}=\cfrac{30.48}{1.3}\implies 1.3=30.48f \\\\\\ \cfrac{1.3}{30.48}=f\implies 0.04265091863517060367 \approx f$
