You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

Answer:

47.5%  is 19 of the 40 .

Step-by-step explanation:

As given

19 is a part value of 40.

Let us assume that the x % is 19 of the number 40.

Now written x % in the decimal form.

[tex]= \frac{x}{100}[/tex]

Than the equation becomes

[tex]\frac{x\times 40}{100} = 19[/tex]

Solving the above

[tex]\frac{19\times 100}{40} = x[/tex]

[tex]\frac{1900}{40} = x[/tex]

x = 47.5%

Therefore  47.5%  is 19 of the 40 .
