Question 804974

amounts are proportional:

{{{12 ounce :120 milligrams=16 ounce :x  }}}

{{{12  *x  =16  *120  }}}

{{{12x=16*120}}}

{{{ x=16*120/12}}}

{{{ x=16*10}}}

 {{{x=160 }}} milligrams

or, you can do it this way:

if you know a {{{12}}} ounce cup of coffee has {{{120}}} milligrams, than you know that {{{1}}} ounce has {{{120 milligrams/12=10milligrams}}}

consequently,a {{{16}}} ounce cup will have {{{16*10milligrams=160milligrams}}}
