The sum of a negative number, 1/4 of the negative number, and 7/16 of the negative number is -13 1/2.
:
let x = the number (which will turn out to be negative)
Change -13 {{{1/2}}} to improper fraction {{{-27/2}}}
:
x + {{{1/4}}}x + {{{7/16}}}x = {{{-27/2}}}
multiply equation by 16, cancel the denominators
16x + 4(x) + 7(x) = 8(-27)
27x = -216
x = -216/27
x = -8
:
 What is the negative number? -8
