the question asks for you to make 400 grains and because the units are the same you can just divide 10/400 and get 0.025 and to get a percentage just multiply by 100 and the percent is 2.5%

if 1 gm = 15.4gr then 10gr=?
by: sheila

you said that 10gr=0.065gm, but i think that may be wrong.

if 1 gm= 15.4gr, then 10 gr = 0.65gm

we will change grains into grams first :


10 grains = 0.65grams as 1grain=0.065gram

10 grain/410 grain = x/100 % formula

so

0.65/26.65=x/100
=2.4%

or

do not convert

just do as it is

10/410=x/100
2.4%

if u have the answer and it is right then please comment back...thanks
