Помогите математику пожалуйста ном 68

Answer 1

a, (-29/8 + 38/5) - (54/5 - 35/4)

=   159/40 - 41/20

= 77/40

b,  -(49/9 -77/12) + (-11/3 - 5/3)

=    35/36 - 16/3

=     -157/36

c,  (24/5 - 73/14) - (-143/35 + 148/35)

=   -29/70 - 1/5

=    39/70

d, 1 - 1/2 - 1/3 + 1/2 - 1/4 +1/3 - 1/5 + 1/4

=  1 - (1/2 - 1/2) - (1/3 - 1/3) - (1/4 - 1/4) - 1/5

=  1 - 1/5

=   4/5
