What is the value of this expression in decimal form? | |||
<cmath>\frac{44}{11} + \frac{110}{44} + \frac{44}{1100}</cmath> | |||
<math>\textbf{(A) } 6.4\qquad\textbf{(B) } 6.504\qquad\textbf{(C) } 6.54\qquad\textbf{(D) } 6.9\qquad\textbf{(E) } 6.94</math> | |||
==Solution 1== | |||
We see that <math>\frac{44}{11}</math> is <math>4</math>; | |||
<math>\frac{110}{44}</math> simplifies to <math>\frac{5}{2}</math>, which is <math>2.5</math>; | |||
and <math>\frac{44}{1100}</math> simplifies to <math>\frac{1}{25}</math>, which is <math>0.04</math>; | |||
<math>4+2.5+0.04</math> reveals <cmath>\frac{44}{11} + \frac{110}{44} + \frac{44}{1100}</cmath> is <math>\boxed{\text{(C)\ 6.54}}</math>. | |||
