c) 2,75 + 2/7
d) 0,125 - 1/9
e) 3 1/3 - 3,3
f) 1 1/5 - 0,09

Answer 1

A) 3,6 + 2/3 = 3 6/10 + 2/3 = 3 18/30 + 20/30 = 3 38/30 = 4 8/30 = 4 4/15
b) 4 1/8 - 1,11 = 4,125 - 1,11 = 3,015
c) 2,75 + 2/7 = 2 3/4 + 2/7 = 2 21/28 + 8/28 = 2 29/28 = 3 1/28
d) 0,125 - 1/9 = 1/8 - 1/9 = 9/72 - 8/72 = 1/72
e) 3 1/3 - 3,3 = 3 1/3 - 3 3/10 = 3 10/30 - 3 9/30 = 1/30
f) 1 1/5 - 0,09 = 1,2 - 0,09 = 1,11
