Answer 2

Step-by-step explanation:

$5 \frac{1}{2} + 3 \frac{1}{5} \\ = \frac{11}{2} + \frac{16}{5} \\ = \frac{55 + 32}{10} \\ = \frac{87}{10} \\ = 8 \frac{7}{10} \\ \\ \\ = 5 \frac{1}{2} - 3 \frac{1}{5} \\ = \frac{11}{2} - \frac{16}{5} \\ = \frac{55 - 32}{10} \\ = \frac{23}{10} \\ = 2 \frac{3}{10}$

let x be the number to be subtracted to get 23/10

$\frac{87}{10} - x = \frac{23}{10} \\ x = \frac{87}{10} - \frac{23}{10} \\ x = \frac{87 - 23}{10} \\ x = \frac{64}{10} \\ x = \frac{32}{5} \\ x = 6 \frac{2}{5}$

we need to subtract 6 2/5

hope you get your answer
