Question

4-7/12+1 5/6+2 1/3-1 1/4

Answer 1

Задание: Решить пример с дробями по действиям.
4 - $frac{7}{12}$ + $1 frac{5}{6}$ + $2frac{1}{3} - 1 frac{1}{4}$ = $6 frac{1}{3}$
1) 4 - $frac{7}{12}$ = $frac{48}{12} - frac{7}{12} = frac{41}{12}$
2) $frac{41}{12} + 1 frac{5}{6} = frac{41}{12} + frac{11}{6} = frac{41}{12} + frac{22}{12} = frac{63}{12}$
3) $frac{63}{12} + 2 frac{1}{3} = frac{63}{12} + frac{7}{3} = frac{63}{12} + frac{28}{12} = frac{91}{12}$
4) $frac{91}{12} - 1frac{1}{4} = frac{91}{12} - frac{5}{4} = frac{91}{12} - frac{15}{12} = frac{76}{12} = frac{19}{3} = 6frac{1}{3}$
