в)6 11/12-3 1/6-1 1/4=?
г)3 7/9-1 5/18+3 1/2=?

Answer 1

а)3 5/16+1/4-2 1/16=3 5/16+4/16-2 1/16=1 8/16=1 1/2

б)1/8+2 3/5+2 7/8=5/40+2 24/40+2 35/40=4 64/40=5 3/5

в)6 11/12-3 1/6-1 1/4=6 11/12-3 2/12-1 3/12=2 1/2

г)3 7/9-1 5/18+3 1/2=3 14/18-1 5/18+3 9/18=6

Answer 2

$1 \ frac{53}{16} + frac{1}{4} - frac{33}{16} = frac{3}{2} = 1 frac{1}{2} \ \ 2 \ frac{1}{8} + frac{13}{5} + frac{23}{8} = frac{28}{5} = 5 frac{3}{5} \ \ 3 \ (6 - 3 - 1) + ( frac{11}{12} - frac{1}{6} - frac{1}{4} ) = 2 + frac{1}{2} = 2 frac{1}{2} = 2.5 \ \ 4 \ 3 + frac{7}{9} - (1 + frac{5}{18} ) + 3 + frac{1}{2} = 3 + frac{7}{9} - 1 - frac{5}{18} + 3 + frac{1}{2} = (3 - 1 + 3) + ( frac{7}{9} - frac{5}{18} + frac{1}{2} ) = 5 + 1 = 6$
