38% basically means [tex] \frac{38}{100} [/tex] right?
If we let the unknown number be [tex]N[/tex], then
N x [tex] \frac{38}{100} [/tex] = 19
Just reverse it now!
N x [tex] \frac{38}{100} [/tex] = 19
N = 19 / [tex] \frac{38}{100} [/tex]
N = 19 x [tex] \frac{100}{38} [/tex]
N = 50
Therefore, 19 is 38% of 50
