Question

What number is 0.4% of 82.1

Answer 1

uythis we can write as:

x=0.4%*82.1

and now we count:)

I like to change my percent into fractions:

x=
`(0.4)/(100)*82.1`

ill multiply the fraction by 10 on nominatoer and denominator:

x=
`(4)/(1000)*82.1`


x=
`(4*82.1)/(1000)`

calculate the mupliplication:

x=
`(328.4)/(1000)`

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!
