Question

2% от 48
25% от 40
2/3 от x =2,4; x = ?

Answer 1

2% от 48  =  48 : 100 * 2 = 0,96

=======

25% от 40  =  40 : 100 * 25 = 10

=======

$\tt\displaystyle\frac{2}{3}x=2,4$

$x=2,4:\tt\displaystyle\frac{2}{3}$

$x=2\tt\displaystyle\frac{4}{10}*\frac{3}{2}$

$x=2\tt\displaystyle\frac{2}{5}*\frac{3}{2}$

$x=\tt\displaystyle\frac{12}{5}*\frac{3}{2}$

$x=\tt\displaystyle\frac{36}{10}=\frac{18}{5}=3\frac{3}{5}=3,6$
