a) 2 1/3 + 1 1/4 + 1 5/2 = 2 1/3 + 1 1/4 + 3 1/2 = 2 4/12 + 1 3/12 + 3 6/12 = 5 13/12 = 6 1/12
b) 1 4/5 + 2,75 = 1,8 + 2,75 = 4,55
c) 3 2/5 - 1 5/6 = 3 12/30 - 1 25/30 = 2 42/30 - 1 25/30 = 1 17/30
d) 4 1/5 - 1,625 = 4,02 - 1,625 = 2,395
e) 5,25 - 3 5/6 = 5 1/4 - 3 5/6 = 5 6/24 - 3 20/24 = 4 30/24 - 3 20/24 = 1 10/24 = 1 5/12
f) 1 3/5 - 0,6 = 1,6 - 0,6 = 1
g) 2 1/2 * 3 2/3 = 5/2 * 11/3 = 55/6 = 9,16
h) 3,5 * 1 2/3 = 3,5 * 1,66 = 5,81
i) 2 1/2 * 4 * 3/5 = 5/2 * 4/1 * 3/5 = 20/2 *3/5 = 60/10 = 6
j) 1 3/7 * 1,25 = 10/7 * 5/4 = 50/28 = 1,79 [ w przybliżeniu ]
mam nadzieję że pomogłam . ;D
