uythis we can write as:
x=0.4%*82.1
and now we count:)
I like to change my percent into fractions:
x=[tex] \frac{0.4}{100}*82.1 [/tex]
ill multiply the fraction by 10 on nominatoer and denominator:
x=[tex] \frac{4}{1000}*82.1 [/tex]
x=[tex] \frac{4*82.1}{1000} [/tex]
calculate the mupliplication:
x=[tex] \frac{328.4}{1000} [/tex]
and write as a decimal fraction:
x=0.3284 (you move the point by as many places as there are 0s in the denominatorr)
this is the resul!
