Answer 2

a)6 1/2 : 1/2 + 2 1/5= 13/2 : 1/2 + 2 1/5= 13/2 *2 + 2 1/5= 13 + 2 1/5= 15 1/5

b)3 3/3 + 1 1/2 * 2 1/3= 4 + 3/2*7/3 = 4+ 7/2= 4+3,5 = 7 1/2

c)5 1/2 - 1 1/3 : 1 2/5= 11/2 - 4/3 : 7/5 = 11/2 - 4/3 * 5/7 = 11/2 - 20/21 = 231/42 - 40/42= 191/42 = 4 23/42

d)1 7/5 : 2 2/3 + 1 1/6=12/5 : 8/3 + 7/6= 12/5 *3/8 + 7/6 = 9/10 + 7/6 = 54/60 + 70/60 = 124/60 = 2 4/60= 2 1/15

e)3 3/4 + 1  1/4 : 2 3/5= 15/4 + 5/4 : 13/5 = 15/4+ 5/4 * 5/13 = 15/4 + 25/52= 195/52 + 25/52= 220/52 = 4 12/52 = 4 3/13
