Question

4-2/3+3 5/12-2 1/4помогите решить

Answer 1

4-2/3+3 5/12-2 1/4= 3,5

1) $4- frac{2}{3} = frac{4}{1} - frac{2}{3} = frac{12}{3} - frac{2}{3} = frac{10}{3}$=3 1/3

2) $3 frac{5}{12} - 1 frac{1}{4} = frac{41}{12}- frac{5}{4} = frac{41}{12} - frac{15}{12} = frac{26}{12}= frac{13}{6}=2 frac{1}{6}$

3) $frac{10}{3} + frac{13}{6} = frac{20}{6} + frac{13}{6} = frac{33}{6} = 3 frac{3}{6} =3 frac{1}{2}=3,5$
