The word "of" means to multiply in mathematical terms (if in case you didn't know)
So, lets begin the steps to find out what your answer is!
[tex]38(400) = ? [/tex]
[tex]38% = .38[/tex]
[tex] \frac{38}{100} [/tex] = .38 ; 0.38 ÷ 100 = 0.38
We take the outcome of the division problem and multiply by 400
[tex].38(400)[/tex]
Now, finally we have found your result of this whole entire problem which is :[tex]152[/tex]
[tex]Good Luck! [/tex]
