Find Common Denominator: To add two fractions, we need to have a common denominator. The denominators here are 5 and 8. The least common multiple (LCM) of 5 and 8 is 40.Convert to Equivalent Fractions: We convert each fraction to an equivalent fraction with a denominator of 40. For 11/5, we multiply both the numerator and the denominator by 8 to get (11*8)/(5*8) = 88/40. For 41/8, we multiply both the numerator and the denominator by 5 to get (41*5)/(8*5) = 205/40.Add the Fractions: Now we can add the two fractions: 88/40 + 205/40.Simplify the Fraction: Adding the numerators gives us 88 + 205 = 293. The denominator remains 40. So, the sum of the two fractions is 293/40.To simplify the fraction, we can divide the numerator by the denominator to get a mixed number. 293 divided by 40 is 7 with a remainder of 13. So, 293/40 is equal to 7 13/40.

\frac{11}{5} +\frac{41}{8}

Find Common Denominator: To add two fractions, we need to have a common denominator. The denominators here are $5$ and $8$ . The least common multiple (LCM) of $5$ and $8$ is $40$ .
Convert to Equivalent Fractions: We convert each fraction to an equivalent fraction with a denominator of $40$ . For $\frac{11}{5}$ , we multiply both the numerator and the denominator by $8$ to get $\left(\frac{11\times8}{5\times8}\right) = \frac{88}{40}$ . For $\frac{41}{8}$ , we multiply both the numerator and the denominator by $5$ to get $\left(\frac{41\times5}{8\times5}\right) = \frac{205}{40}$ .
Add the Fractions: Now we can add the two fractions: $\frac{88}{40} + \frac{205}{40}$ .
Simplify the Fraction: Adding the numerators gives us $88 + 205 = 293$ . The denominator remains $40$ . So, the sum of the two fractions is $\frac{293}{40}$ .
Simplify the Fraction: Adding the numerators gives us $88 + 205 = 293$ . The denominator remains $40$ .
