As part of a lesson on earthquakes, a science class is researching the movement of a nearby fault line. The fault line moved 2 3/5 inches during the past year and 1 1/10 inches the year before. How far did the fault line move in all? Write your answer as a fraction or as a whole or mixed number. _____ inches

Convert to Improper Fractions: Convert mixed numbers to improper fractions for easier addition. 2 3/5 = (5*2 + 3)/5 = 13/5, 1 1/10 = (10*1 + 1)/10 = 11/10,Add Improper Fractions: Add the two improper fractions. 13/5 + 11/10, To add, find a common denominator. The least common multiple of 5 and 10 is 10. 13/5 = (13*2)/10 = 26/10, 26/10 + 11/10 = 37/10,Convert Back to Mixed Number: Convert the improper fraction back to a mixed number. 37/10 = 3 remainder 7, So, 37/10 = 3 7/10,

_____ inches

Convert to Improper Fractions: Convert mixed numbers to improper fractions for easier addition. $\newline$ $2 \frac{3}{5} = \frac{(5\times2 + 3)}{5} = \frac{13}{5}$ , $\newline$ $1 \frac{1}{10} = \frac{(10\times1 + 1)}{10} = \frac{11}{10}$ ,
Add Improper Fractions: Add the two improper fractions. $\newline$ $\frac{13}{5} + \frac{11}{10}$ , $\newline$ To add, find a common denominator. The least common multiple of $5$ and $10$ is $10$ . $\newline$ $\frac{13}{5} = \frac{(13\times2)}{10} = \frac{26}{10}$ , $\newline$ $\frac{26}{10} + \frac{11}{10} = \frac{37}{10}$ ,
Convert Back to Mixed Number: Convert the improper fraction back to a mixed number. $\newline$ $\frac{37}{10} = 3$ remainder $7$ , $\newline$ So, $\frac{37}{10} = 3 \frac{7}{10}$ ,
