Answer 1

$1) 3 - frac{8}{20} = frac{3}{1} - frac{8}{20} = frac{60}{20} - frac{8}{20} = frac{52}{20}$

2) $4 - 2frac{2}{11} = frac{4}{1} - frac{23}{11} = frac{44}{11} - frac{23}{11} = frac{21}{11}$

3)$5 frac{2}{5} - frac{4}{5} = frac{27}{5} - frac{4}{5} = frac{23}{5}$

4) $9 frac{16}{25} - frac{6}{25} = frac{241}{25} - frac{6}{25} = frac{235}{25}$

5) 13 - 14 = 412 - 312 = 112

6) 23 - 17 = 1421 - 321 = 1121

7) 35 + 310 = 610 + 310 = 910

Answer 2

3 - 8/20 = 2 20/20 - 8/20 = 2 12/20 = 2 3/5
4 - 2 2/11 = 3 11/11 - 2 2/11 = 1 9/11
5 2/5 - 4/5 = 4 7/5 - 4/5 = 4 3/5
9 16/25 - 6/25 = 9 10/25 = 9 2/5
1/3 -1/4 = 4/12 - 3/12 = 1/12
2/3 - 1/7 = 14/21 - 3/21 = 11/21
3/5 + 3/10 = 6/10 + 3/10 = 9/10
