Suppose that A = D + E and that D/A = 0.80. Solve for D/E.
Round your answer to two (2) decimal places. For example, record 0.879248 as 0.88.
If your answer is a negative number, place a minus sign before the number with no space berween the minus sign and the number. That is, record negative 1.38245326 as -1.38.
