Question

1) 4,8x+2 1/6x-3 3/4x
2) -1 5/8m+2 5/12a-7/16m+3 1/6a
3) 3 8/15x-5 1/2y-1 1/10x-2 5/6y

Answer 1

Пошаговое объяснение:

1)

4,8х+2 1/6 х-3 3/4 х=4 4/5 х+13/6 х-15/4 х=

=24/5 х+13/6х-15/4х=

=288/60х+130/60х-225/60х= 193/60х=

= 3 13/60 х

2)

- 1 5/8m+2 5/12a-7/16m+3 1/6a=

= - 1 10/16m-7/16m+2 5/12a+3 2/12a=

= - 1 17/16m+5 7/12a= - 2 1/16m+5 7/12a=

= - 33/16m+67/12a

3)

3 8/15x-5 1/2y-1 1/10x-2 5/6y=

=3 16/30x-1 3/30x-5 3/6y-2 5/6y=

=2 13/30x-7 8/6y=2 13/30x-7 4/3y=

=2 13/30x-8 1/3y=73/30x-25/3y
