Question

(3 1/3+2,5)*(4,6-2 1/3)

Answer 1

(3 1/3+2,5)*(4,6-2 1/3)=13 2/9
3 1/3+2,5=3 1/3+2 5/10=5 5/6
4,6-2 1/3=4 6/10-2 1/3=2 4/15
5 5/6*2 4/15=119/9=13 2/9

Answer 2

$(3frac{1}{3} +2,5)*(4,6-2 frac{1}{3} )$$13 frac{2}{9}$

$1)3 frac{1}{3} +2 frac{1}{2} =3 frac{2}{6} +2 frac{3}{6} =5 frac{5}{6}$

$2)4 frac{3}{5} -2 frac{1}{3} =4 frac{9}{15} -2 frac{5}{15} =2 frac{4}{15}$

$3)5 frac{5}{6} *2 frac{4}{15} = frac{35*34}{6*15} = frac{7*17}{3*3} = frac{119}{9} =13 frac{2}{9}$
