(- 12) × (- 1 / 3) - (- 4) × 1 / 3 + 11 × (- 1 / 3) I've been thinking about this question for a long time. I really can't write it (- three and one seventh) is negative three and one seventh

(- 12) × (- 1 / 3) - (- 4) × 1 / 3 + 11 × (- 1 / 3) I've been thinking about this question for a long time. I really can't write it (- three and one seventh) is negative three and one seventh

(- 12) × (- 1 / 3) - (- 4) × 1 / 3 + 11 × (- 1 / 3)
=12 × three and one seventh + 4 × three and one seventh - 11 × three and one seventh
=(12 + 4-11) × three and one seventh
=5 × 3 and 1 / 7
=15 and 5 / 7

It's a question of thinking. How many questions should I fill in here? How can I work it out

It's 3, because 18 minus 7 equals 11, 7 minus 4 equals 3, 11 plus 3 equals 14, 17 minus 14 equals 3, so it's 3

1-8 of 1-6 of 1 =? 7 of 5 + 1 and 8 of 1 + 3 and 2 of 1 =?

17/24
299/56

-3.2 + 3 and 3 / 7-6.8 + 5 and 4 / 7=

Original form
=-(3.2 + 6.8) + (3 and 7 / 3 + 5 and 7 / 4)
=-10+9
=-1
