Answer 1

Moim zdaniem powinno być tak ale nie wiem czy dobrze
a) ( 5/3 - 1/3 + 7/3 ) * 3 = 11/3 * 3 = 33/3 = 11

b) ( 11/2 - 5/2 + 15/2 ) * 2 = 22/2 * 2 = 44/2 =  22

c) 3 2/3 + 3 * 1 1/3 = 3 2/3 + 12/3 = 3 14/3 = 7 2/3

d) 3 1/4 * 4 - 2 3/4 = 13 - 2 3/4 = 10 1/4

e) 2 1/5 * 5 - 4 2/5 + 1 1/5 = 11 - 4 2/5 + 1 1/5 = 6 3/5 + 1 1/5 = 7 4/5

f) 7 1/2 - 3 + 2 * 3/4 = 7 1/2 - 3 + 6/4 = 4 1/2 + 6/4 = 9/2 + 6/4 = 18/4 + 6/4 =        24/4 = 6

g) 2 1/2 * 3 + 4 * 1 1/2 = 7 1/2 + 4 = 11 1/2

h) 2 1/4 * 2 + 3 3/4 = 4 2/4 + 3 3/4 = 8 1/4

i) 9 - 1 3/5 * 4 = 9 - 8 = 1

Answer 2

a) ( 5/3 - 1/3 + 7/3 ) * 3 = 11/3 * 3 = 33/3 = 11

b) ( 11/2 - 5/2 + 15/2 ) * 2 = 22/2 * 2 = 44/2 =  22

c) 3 2/3 + 3 * 1 1/3 = 3 2/3 + 12/3 = 3 14/3 = 7 2/3

d) 3 1/4 * 4 - 2 3/4 = 13 - 2 3/4 = 10 1/4

e) 2 1/5 * 5 - 4 2/5 + 1 1/5 = 11 - 4 2/5 + 1 1/5 = 6 3/5 + 1 1/5 = 7 4/5

f) 7 1/2 - 3 + 2 * 3/4 = 7 1/2 - 3 + 6/4 = 4 1/2 + 6/4 = 9/2 + 6/4 = 18/4 + 6/4 =        24/4 = 6

g) 2 1/2 * 3 + 4 * 1 1/2 = 7 1/2 + 4 = 11 1/2

h) 2 1/4 * 2 + 3 3/4 = 4 2/4 + 3 3/4 = 8 1/4

i) 9 - 1 3/5 * 4 = 9 - 8 = 1

Mam nadzieję, że pomogłam ;D
