$x = 500$

$1.25x = 625$

$x = 625 / 1.25$

$x = 500$

The number is 500.

let the number be $x$

$125% xx x =625$

$125/100 x = 625" "larr$ isolate x#

$x = 625 xx 100/125$

$x = (cancel625^5 xx 100)/cancel125$

$x = 500$

You can also use direct proportion

$125/100 = 625/x$

$x = (625xx100)/125$

$x = 500$
