Answer 2

A) 0,9÷1/5+1/3-3/5=9/10:5/1+1/3-3/5=9/1+1/3-3/5=135/15+5/15-9/15=140-9/15=131/15=8 11/15

B)2 1/7× 1,6×2 1/3=2 1/7*1 6/10*2 1/3 = 15/7*16/10*7/3=8

C)6 2/3× (0,25+1/5) = 20/3*(25/100+1 50/100) = 20/3*1 75/100 = 35/3 = 11 2/3

D)3 1/3 -1/3× 0,6 = 3 1/3-1/3*6/10=3 1/3 – 1/5 = 10/3 – 1/5 = 50/15 – 3/15 = 47/15 = 3 2/15

E)4,5× 5 5/9+6,4×3/8= 45/10 * 50/9 + 6 4/10 * 3/8 = 25/1 + 64/10 * 3/8= 25/1+12/5=125/5+12/5=137/5=27 2/5
