First, change the decimal to a fraction by putting it over 1000:

Now find a common denominator of 625 and 1000. The simplest to find and divide by is 5. So begin by dividing them each by five until you have a completely simplified fraction:

The answer is 4 5/8

Step-by-step explanation:

Use triangle congruency:

BC=EC, AC=DC - Given

m∠DCE = m∠ACB because they are vertical angles

Therefore ΔABC ≅ ΔDEC because of Side-Angle-Side congruency

AB=DE because corresponding parts of congruent triangles are also congruent (CPCTC)
